Force and Motion Review Amplify ******

Front

What is force?

Back

Force is a push or pull on an object that can cause it to change its velocity (speed or direction).

Front

What is motion?

Back

Motion is the change in position of an object over time.

Front

What is mass?

Back

Mass is the amount of matter in an object, usually measured in kilograms or grams.

Front

How does mass affect force?

Back

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

Front

What is Newton's First Law of Motion?

Back

An object at rest will stay at rest, and an object in motion will stay in motion at a constant speed and in a straight line unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can be a change in speed or direction.

Front

What is the relationship between force and acceleration?

Back

The greater the force applied to an object, the greater the acceleration produced, assuming mass remains constant.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object, caused by the contact between two surfaces.
