Forces and Newton's Laws Test Review

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

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 (F=ma).

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is the definition of force?

Back

A push or pull on an object resulting from the object's interaction with another object.

Front

What are the units of force in the SI system?

Back

Newtons (N).

Front

What is the relationship between mass and acceleration according to Newton's 2nd Law?

Back

As mass increases, acceleration decreases for a given force.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces result in a change in the motion of an object.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = Net Force (F) / Mass (m).

Front

What is inertia?

Back

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

Front

How do action and reaction forces relate to each other?

Back

Action and reaction forces are equal in size but opposite in direction.
