It is possible to move on a curved path with zero acceleration
.
Is it possible to move on a curve with zero acceleration?
It is possible to move on a curved path with zero acceleration
.
Can a car go around a curve without acceleration?
An object, for example, can be moving at a constant speed around a circular track, but its velocity must be constantly changing in order for the object to be constantly changing direction. The magnitude of the velocity does not change, but the direction does.
Yes.
What happens when there is 0 acceleration?
If there is no acceleration, then
the object will move with a constant velocity
. Mathematically, we can look at Newton’s second law and the formula for acceleration. We know that the force is zero. Since we know that the mass cannot be zero, the acceleration must be zero.
Can u go around a curve with constant acceleration?
Can you go around a curve with constant acceleration?
No
, because the vector always points to the center of the circle and you are always changing the direction of that vector.
Is it possible for an object to move in a curved path in the absence of a force discuss why or why not with an example?
For a path to move at circular arc, there must be some force to provide it centripetal force to remain it in circular path.
It is not possible to have motion along curved path without any force.
Does a car accelerate when it goes around a corner?
As a car goes around a corner, because its direction changes, the velocity must change.
A change in velocity requires acceleration and it is centripetal force which causes this “centripetal” acceleration.
Is turning a corner acceleration?
You experience this acceleration yourself when you turn a corner in your car
—if you hold the wheel steady during a turn and move at constant speed, you are in uniform circular motion. What you notice is a sideways acceleration because you and the car are changing direction.
Is it possible for a car to travel around a curve on a frictionless surface?
No, a car cannot steer on a frictionless surface
.
Can an object moving without acceleration?
4) a) Can an object be moving when its acceleration is zero? If so, give an example.
Yes, an object that was set in motion in the past by some force, but that is no longer being acted on by a net force, is moving but with zero acceleration
, i.e. it is moving at constant velocity.
Does zero acceleration mean the object is at rest?
Finding the acceleration
Thus, even though the velocity of an object at rest must be zero,
acceleration can clearly be non-zero for objects at rest
. A particle that is thrown vertically upwards stops momentarily at the highest point of motion.
Which has a zero acceleration an object?
Anytime the velocity is constant
, the acceleration is zero. For example, a car traveling at a constant 90 km/h in a straight line has nonzero velocity and zero acceleration.
Can a body moving at a constant speed have acceleration?
Answer and Explanation: If a body is moving with constant speed in a circle, then
yes, that body has acceleration
.
How would it be possible for an object to be traveling with constant speed and still be accelerating?
An object which experiences either a change in the magnitude or the direction of the velocity vector can be said to be accelerating. This explains why an object moving in a circle at constant speed can be said to accelerate –
the direction of the velocity changes
.
What happens to the acceleration of object moving in uniform circular motion?
We know from kinematics that acceleration is a change in velocity, either in magnitude or in direction or both. Therefore, an object undergoing uniform circular motion is
always accelerating
, even though the magnitude of its velocity is constant.
Can an object around a curve without any force acting upon it?
Explain. [8] Can an object go round a curve without any force acting on it? [9] When you push a cart across a lawn at a constant velocity you have to exert a steady force. However, Newton’s 1st Law says that
motion at constant velocity requires no force
.
Can you make an object go around a curve without applying any force explain your answer?
Answer and Explanation:
No, it is not possible to move in a curved path in the absence of the force.
Which conditions describe a box with zero acceleration?
By Newton’s second law of motion,
if there is a nonzero net force
there is an acceleration. If there is no acceleration then the net force is zero. In the situation you describe, where the box has no acceleration, there must be another force balancing Fapp otherwise there will be an acceleration.
When a car rounds a corner at constant speed its acceleration is zero?
Because the direction of a car changes when rounding a corner at a constant speed, there is a non-zero acceleration. As such, the following statement is FALSE:
When a car rounds a corner at a constant speed, its acceleration is zero.
How do you accelerate through a corner?
Can there be negative acceleration?
According to our principle, when an object is slowing down, the acceleration is in the opposite direction as the velocity. Thus,
this object has a negative acceleration
.
In which of the following situations is the object not accelerating?
Objects are NOT accelerating
if they are traveling in a straight line at constant speed
.
Do cars accelerate in a turn?
In fact,
a car accelerates whenever its velocity is changed by either changing the speed or the direction of the car’s motion
. So, even if you are driving your car at a constant speed while turning around a corner, you are still accelerating.
What is acceleration at Turning point?
At a turning point,
its velocity is zero
. Example: an object is tossed into the air. The initial velocity is +9.8m/s and continues to be. positive until it reaches a maximal height.
What is the maximum speed at which a car can round a curve?
If the mass of the car is m, the maximum friction force (which is the centripetal force) equals μ,FN or 0.80mg, this arises when the car is on the verge of skidding sideways. Therefore, the maximum speed is given by. mv2r=0.80mg or v=√0.80gr=√(0.80)(9.81 m/s2)(25 m)=
14 m/s
.
What is an unbanked curve?
Unbanked Curves. An unbanked curve is simply
a curve (or a turn) that lies flat on the ground (parallel to the horizontal)
. Whenever a car travels along such a curve, there is a force of friction that acts on the car to keep it turning in a circular pathway.
Is it possible for a car to move in a circular path in such a way that it has a tangential acceleration but no centripetal acceleration?
No
, because moving in a circular track implies a changing in the direction of motion, which leads to the existence of the centripetal acceleration.
What happens to an objects speed if it travels with zero acceleration?
There are two conditions where acceleration can be zero, they are: Displacement equal to zero. For an object at rest, the velocity of the object is zero and hence the acceleration of an object will also be equal to zero.
The initial and final velocity of the object is the same and remains constant
.
Which graph represents an object with zero acceleration?
Does 0 velocity mean 0 acceleration?
Acceleration is the rate of change of velocity of an object with respect to the time over which this change occurs.
It is possible to have a non-zero value of acceleration when the velocity of a body is zero
.
What is an example of zero acceleration?
So,
a jet moving with a constant velocity at 800 miles per hour along a straight line
has zero acceleration, even though the jet is moving really fast, since the velocity isn’t changing. When the jet lands and quickly comes to a stop, it will have acceleration since it’s slowing down.
Can a body have zero acceleration with constant speed give an example?
Can a body have constant speed and zero acceleration?
Complete answer:
Again, since the acceleration is the rate of change of velocity of a body with time,
if the velocity is constant, the acceleration of the body will be zero
. A body can move with a constant speed but can have a changing velocity due to a change in its direction.
Is it possible to round a curve with constant acceleration as in case of projectile?
Yes, it is impossible to go around the curved path with zero acceleration
. Acceleration is change in velocity. And velocity( speed+ direction) changes at every point in a curved path because there is change in direction at every point.
Is it possible to move on a curved path with variable acceleration?
<br> (iii) Variable acceleration on curved path is <br>
definitely possible
.
Is acceleration the rate of change in velocity?
To be specific,
acceleration is defined to be the rate of change of the velocity
.
