Newton's Three Laws of Motion

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 the formula for Newton's Second Law of Motion?

Back

F = m x a (Force equals mass times acceleration).

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

What are balanced forces?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

How does mass affect acceleration according to Newton's Second Law?

Back

If mass increases, acceleration decreases for the same amount of force applied.

What happens to a stationary object when balanced forces act on it?

Back

It remains stationary.

What happens to a moving object when balanced forces act on it?

Back

It continues to move at a constant velocity.
