What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is measured in meters per second (m/s).

Front

How do you calculate average speed?

Back

Average speed = Total distance / Total time.

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv, where p is momentum, m is mass, and v is velocity.

Front

What does the Law of Conservation of Momentum state?

Back

The Law of Conservation of Momentum states that the total momentum of a closed system remains constant if no external forces act on it.

Front

What is centripetal force?

Back

Centripetal force is the force that keeps an object moving in a circular path, directed towards the center of the circle.

Front

What is Newton's First Law of Motion?

Back

Newton's First Law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass, expressed as F = ma.

Front

What is Newton's Third Law of Motion?

Back

Newton's Third Law states that for every action, there is an equal and opposite reaction.

Front

What is a force?

Back

A force is a push or pull that one body exerts on another body.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.
