Physics Review

Front

What is force?

Back

A push or pull exerted on an object.

Front

What is centripetal force?

Back

The force that keeps an object moving in a circular path.

Front

What is the rate of gravitational acceleration?

Back

9.8 m/s².

Front

What is the difference between distance and displacement?

Back

Distance is the total path traveled, while displacement is the shortest path from the starting point to the endpoint.

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 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 (F=ma).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is kinetic energy?

Back

The energy of an object due to its motion, calculated as KE = 1/2 mv².

Front

What is potential energy?

Back

The energy stored in an object due to its position or configuration, commonly gravitational potential energy (PE = mgh).

Front

What is the formula for calculating work?

Back

Work is calculated as W = Fd cos(θ), where F is the force, d is the distance, and θ is the angle between the force and the direction of motion.
