Force, Energy, Heat, and Motion

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is the energy an object has when it is at rest and has the potential to move.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is the formula for gravitational potential energy (GPE)?

Back

The formula for gravitational potential energy is GPE = mass (kg) × gravity (9.8 m/s²) × height (m).

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, force (F) is equal to mass (m) multiplied by acceleration (a): F = m × a.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction. It is a vector quantity.

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 includes both speed and direction.

Front

What is work in physics?

Back

Work is done when a force causes an object to move. It is calculated as Work = Force × Distance.

Front

What is the formula for calculating work?

Back

The formula for calculating work is Work = Force (N) × Distance (m).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be caused by an increase or decrease in speed or a change in direction.
