It
always takes force
to change the motion of an object. Explanation: According to the first law of motion, an object will remain in its position of rest or motion unless it is acted upon by an external force.
What is it called to change an objects motion?
acceleration
. the change in movement; when an object speeds up, slows down, stops, or changes direction. balanced forces.
How can I change the motion of an object?
A force can change the direction
in which an object is moving. A bigger force on an object will produce a bigger change in the motion. A heavier object requires a larger force than a lighter object in order to undergo the same change in motion.
What is the greatest change in motion?
A force is a push or pull that can cause an object to move, stop, or change speed or direction. 3.
The greater the force
, the greater the change in motion.
What are three ways to change the motion of an object?
Answer: The action by a force can cause an object to move or speed up , to slow down , to stop, or
to change direction
.
Does inertia depend on mass?
The tendency of an object to resist changes in its state of motion varies with
mass
. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.
How does motion take place?
Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed, and time. The motion of a body is observed by
attaching a frame of reference to an observer
and measuring the change in position of the body relative to that frame with change in time.
Which affects the motion of an object?
Objects change their motion because unbalanced forces act on them. There are four main factors that affect the motion of objects. These factors are
force, friction, inertia, and momentum
.
Is motion a change in position?
Sometimes an object’s position does change. When it does, the object is in motion. Motion is a
change of position of an object
.
How do you slow down a moving object?
Friction
is a force that occurs when two surfaces slide past one another. The force of friction opposes the motion of an object, causing moving objects to lose energy and slow down. When objects move through a fluid, such as air or water, the fluid exerts a frictional force on the moving object.
Which force can stop a moving object?
Friction
is a force that slows or stops motion. Friction is the resistance to motion created by two objects rubbing against each other (the sled and the snow, for instance). Even air causes friction.
What causes a change in motion answer?
Force
is the cause of change in the state of motion of a body or an object. It is a quantitative description of an interaction that causes a change in an object’s motion. Force can cause an object to move or accelerate, to slow down or decelerate, to stop or to change its direction.
How can you tell that the object is in motion?
An object is in motion if its distance relative to another object is changing. To tell if an object is moving, you
use a reference point
. If an object’s distance from another object [reference point] is changing. A place or object used for comparison to determine if something is in motion.
What does not affect the motion of an object?
balanced forces
do not affect the motion of the object. Unbalanced forces affect the motion and velocity of an object. If forces are in the same direction, how would you calculate net force? If forces are in opposite directions, how would you calculate net force?
What objects have more inertia?
A more massive object
has more inertia than a less massive object. Fast-moving objects have more inertia than slow-moving objects. An object would not have any inertia in a gravity-free environment (if there is such a place). Inertia is the tendency of all objects to resist motion and ultimately stop.
Is angular momentum always conserved?
Just as linear momentum is conserved when there is no net external forces,
angular momentum is constant or conserved when the net torque is zero
.
