Unit 2 Packet 1 - Newton's Laws

Front

A change in velocity over time is called

Back

Acceleration

Front

An object at rest will stay at rest, an object in motion will stay in constant motion unless acted on by:

Back

Force

Front

What is the equation for Newton's second law?

Back

F = ma

Front

If the force on a cart triples, its acceleration does the following:

Back

triples

Front

If a cart acted on by a constant force suddenly triples in mass, what happens to its acceleration?

Back

changes by a third

Front

Units for force: kg, lbs, N, m/s^2

Back

Front

Force and acceleration are:

Back

directly proportional

Front

Force and mass are:

Back

directly proportional

Front

Acceleration and mass are:

Back

inversely proportional

Front

If an object is moving at constant velocity, what is true of the forces on it?

Back

There are balanced forces where the net force is zero
