Dynamics D

Front

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

Back

The 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 the forces acting on an object.

Front

What is the formula for calculating acceleration?

Back

a = F/m, where 'a' is acceleration, 'F' is net force, and 'm' is mass.

Front

If the mass of an object is increased while the net force remains constant, what happens to its acceleration?

Back

The acceleration decreases.

Front

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

Back

Force equals mass times acceleration (F = ma).
