Forces Review

Front

What is Force?

Back

A push or pull acting on an object, measured in Newtons (N).

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 unless acted upon by a net external 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 Net Force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What is Balanced Force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is Unbalanced Force?

Back

Forces that are not equal and opposite, resulting in a change in motion.

Front

How does mass affect acceleration?

Back

An increase in mass results in a decrease in acceleration if the net force remains constant.

Front

What is the formula for calculating acceleration?

Back

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

Front

What happens to acceleration if the net force is doubled?

Back

The acceleration is also doubled.
