Newton's Laws Review

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. In this case, it is 400 N Down.

Front

This equation goes with which law? F = ma

Back

Newton's second law of motion.

Front

As the mass of an object increases, its inertia will ___

Back

increase. Inertia is the resistance of an object to change its state of motion.

Front

What is the unit of measurement for force?

Back

Newtons (N) is the unit of measurement for force.

Front

What is Newton's first law of motion?

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 second 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 third law of motion?

Back

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

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).
