Sir Isaac Newton

Front

What is the term for measuring how quickly something is moving or being done?

Back

Speed

Front

What does an unbalanced force acting on an object change?

Back

It changes the object's speed and direction.

Front

What is Newton's First Law of Motion also known as?

Back

Law of Inertia

Front

What is the rate at which an object changes its speed or direction called?

Back

Acceleration

Front

What is the relationship between force, mass, and acceleration according to Newton's Second Law?

Back

Force equals mass times acceleration (F = ma).

Front

What is an example of an unbalanced force?

Back

A person pushing a stationary car to get it moving.

Front

What happens to an object in motion when no unbalanced forces act on it?

Back

It continues to move at a constant speed in a straight line.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion, while unbalanced forces do.

Front

What is inertia?

Back

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