Forces Review

Front

What does Newton's First Law of Motion state?

Back

An object at rest will not move unless an unbalanced force acts upon it.

Front

What can happen to an object in motion when an unbalanced force acts upon it?

Back

It can speed up, slow down, or change direction.

Front

True or False: A door exerts no force on you when you push it.

Back

False. The door exerts a force on you with equal strength.

Front

How do you calculate net force when forces act in the same direction?

Back

You add the forces together.

Front

What are the variables used in Newton's Second Law of Motion?

Back

Mass, force, and acceleration.

Front

What is a balanced force?

Back

A situation where two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

A force that causes an object to change its motion, either by speeding up, slowing down, or changing direction.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force according to Newton's Second Law?

Back

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

Front

What is friction?

Back

A force that opposes the motion of an object, acting in the opposite direction of the movement.
