Force and Motion review

Front

What is the law of inertia?

Back

An object in motion will stay in motion unless acted upon by a force.

Front

What does it mean if an object is at rest?

Back

The forces acting on the object are balanced.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity.

Front

What are balanced forces?

Back

Equal forces acting on an object in opposite directions that do not change the object's motion.

Front

What is potential energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What happens to an object's motion when unbalanced forces act on it?

Back

The object's motion will change.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object.

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is needed to change its motion.

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = m x a).
