Final Review

Front

What does Newton's 2nd Law of Motion state?

Back

The net force exerted on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

Front

Which celestial body exerts the strongest gravitational force on you?

Back

Earth.

Front

What is NOT considered a force?

Back

Momentum.

Front

In which direction does the acceleration of an object act?

Back

In the same direction as the net force.

Front

What is the definition of gravity?

Back

The attractive force between two objects that depends on their masses and the distance between them.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma).

Front

What is the relationship between mass and weight?

Back

Weight is the force of gravity acting on an object's mass (Weight = Mass x Gravity).

Front

What is static friction?

Back

The force that keeps an object at rest and prevents it from moving when a force is applied.

Front

What is air resistance?

Back

A type of frictional force that opposes the motion of an object through the air.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
