Understanding Force and Motion

Front

What happens to the speed of an object when a force is applied in the direction of its motion?

Back

It speeds up.

Front

Which of these objects will fall faster in a vacuum, where there is no air resistance?

Back

Both fall at the same rate.

Front

What is the term for the tendency of an object to resist a change in its motion?

Back

Inertia.

Front

What is the term for a push or pull on an object?

Back

Force.

Front

If you push a toy car and it starts moving, what kind of force is being applied?

Back

Applied force.

Front

What is the definition of force in physics?

Back

A push or pull that can cause an object to accelerate.

Front

What is inertia and how does it affect motion?

Back

Inertia is the resistance of any physical object to any change in its velocity.

Front

What is the relationship between force and motion?

Back

Force causes changes in the motion of an object.

Front

What is the effect of gravity on falling objects?

Back

Gravity pulls objects toward the center of the Earth, causing them to accelerate downward.

Front

How does air resistance affect the motion of falling objects?

Back

Air resistance opposes the motion of falling objects, slowing them down.
