Front

What is the definition of a force?

Back

A force is a push or pull.

Newton (N).

Front

What is the velocity of a baseball at the highest point when thrown straight up?

Back

0 m/s.

Front

What is Newton's second 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.

Front

How is force calculated according to Newton's second law?

Back

Force = mass × acceleration (F = ma).

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

As mass increases, acceleration decreases if the force is constant.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravitational force only.

Front

What is the acceleration due to gravity near the Earth's surface?

Back

Approximately 9.81 m/s².
