Motion & Forces

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 force.

Front

What does it mean for an object to accelerate?

Back

An object accelerates if it speeds up, slows down, or changes direction.

What is the Law of Conservation of Momentum?

Back

The total momentum of a closed system remains constant if no external forces act on it.

What does Newton's Third Law of Motion state?

Back

For every action, there is an equal and opposite reaction.

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is a balanced force?

Back

A balanced force occurs when 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

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

What is inertia?

Back

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

Front

What is the formula for calculating momentum?

Back

Momentum = Mass x Velocity.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
