Forces and Motion

Front

What are unbalanced forces?

Back

Unequal forces that cause a change in the motion of an object.

Front

What effect does friction have on a moving object?

Back

It causes the moving object to slow down and eventually stop.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest and an object in motion stays in motion until acted upon by an unbalanced force.

Front

What is friction?

Back

A force that opposes motion.

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is Newton's 2nd 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.

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is momentum?

Back

The product of an object's mass and its velocity.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a).
