Front

What happens to acceleration if the net force on a body is doubled?

Back

Acceleration is doubled.

Front

Acceleration is ____________ proportional to mass.

Back

inversely.

Front

Acceleration is ____________ proportional to net force.

Back

directly.

Front

The acceleration of a body is directly proportional to net force and inversely proportional to mass. This is called...

Back

Newton's 2nd Law.

Front

What is Newton's 1st Law?

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 3rd Law?

Back

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

Front

Define net force.

Back

The vector sum of all forces acting on an object.

Front

What is the formula for Newton's 2nd Law?

Back

F = ma (Force equals mass times acceleration).

Front

If mass is doubled while keeping net force constant, what happens to acceleration?

Back

Acceleration is halved.

Front

What is the relationship between force, mass, and acceleration?

Back

Force is directly proportional to acceleration and mass.
