Force and Motion Review

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

What happens to an object when a force is applied?

Back

An object can speed up, slow down, or change direction when a force is applied.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces cause an object to accelerate.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity, which can involve speeding up, slowing down, or changing direction.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces in contact.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the role of mass in motion?

Back

The mass of an object affects how much force is needed to change its motion; heavier objects require more force.
