Yes . Velocity and acceleration need not be in the same direction. A car moving north that slows down, for example, accelerates toward the south. 81.
Can an automobile with a velocity toward the north simultaneously have an acceleration?
Yes, an automobile with a velocity toward the north can have acceleration toward the south . This happens when a moving car driving north applies brakes and slows down.
Is it possible to travel in one direction and accelerate in the opposite direction?
question_answer Answers(1)
Answer: Yes , a body can have acceleration and velocity in opposite directions.
Can a car travel east while accelerating West?
So yes, an object can’t be moving to east and accelerating to the west forever . Eventually the acceleration will bring the object to rest and then start it moving toward the west. However, there can still be a period of time where the object is moving to east while accelerating to the west.
Can a car accelerate by changing direction?
This means that a change in velocity can be a change in magnitude (or speed), but it can also be a change in direction. For example, if a car turns a corner at constant speed, it is accelerating because its direction is changing. The quicker you turn, the greater the acceleration.
Does direction matter for acceleration?
Since acceleration is a vector quantity, it has a direction associated with it . The direction of the acceleration vector depends on two things: whether the object is speeding up or slowing down. whether the object is moving in the + or – direction.
Can an object be moving if its acceleration is zero?
4) a) Can an object be moving when its acceleration is zero? ... 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.
Is it possible for a vehicle to travel around a curve without accelerating?
Is it possible to round a curve with (b) zero acceleration and (c) a constant magnitude of acceleration? ——— (a) Yes. Rounding a curve at constant speed means you are accelerating toward the center of the circle. Even though your speed is constant, your velocity vector is changing, so your acceleration is nonzero .
Why can a car accelerate while traveling at constant speed but not at constant velocity?
An object’s acceleration is the rate its velocity (speed and direction) changes. Therefore, an object can accelerate even if its speed is constant – if its direction changes . If an object’s velocity is constant, however, its acceleration will be zero. ... Since it travels in a straight line, its direction does not change.
Does the acceleration of the cart change as they change the amount of force applied?
states that the acceleration of an object increases with increased force and decreases with increased mass . ... In the left-hand photograph, the force on the cart changes, while the mass of the cart stays the same. In the right-hand photograph, the force on the cart stays the same, while the mass of the cart varies.
Can a body have uniform speed but still have acceleration?
Answer: An object moving in a circular path with uniform speed, i.e covering equal distance in equal amount of time is still under acceleration . Because, the velocity keeps on changing due to continuous change in the direction of motion.
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.
Does slowing down mean negative acceleration?
When a car is slowing down, the acceleration and velocity are in opposite directions. The acceleration is negative . ... A change in velocity is either a change in an object’s speed or its direction. When a moving object changes direction, its velocity changes and it is accelerating.
Is velocity in the same direction as acceleration?
When an object is speeding up , the acceleration is in the same direction as the velocity. Thus, this object has a positive acceleration. In Example B, the object is moving in the negative direction (i.e., has a negative velocity) and is slowing down.
Is acceleration change in velocity or speed?
For all other kinds of motion, both effects contribute to the acceleration. Because acceleration has both a magnitude and a direction, it is a vector quantity. Velocity is also a vector quantity. Acceleration is defined as the change in the velocity vector in a time interval , divided by the time interval.
Does changing speed always involve acceleration?
Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both. ... Any of these would be considered an acceleration since they change velocity.
