Newton's Law Intro Regents

Front

What is the tendency of an object to resist a change in motion?

Back

Inertia

Front

If all objects are struck with the same amount of force, which one will have the greatest acceleration?

Back

The object with the least mass will have the greatest acceleration.

Front

What are the units used to measure force?

Back

Newtons

Front

What is the net force when two forces of 20 N and 20 N act in the same direction?

Back

40 N

Front

What is the Law of Inertia?

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 the formula for calculating force?

Back

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

Front

What happens to the acceleration of an object if the mass increases while the force remains constant?

Back

The acceleration decreases.

Front

What is the relationship between mass and acceleration according to Newton's Second Law?

Back

Acceleration is inversely proportional to mass when force is constant.

Front

What is the Law of Action-Reaction?

Back

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

Front

What is the effect of balanced forces on an object?

Back

The object remains at rest or continues to move at a constant velocity.
