Work, Energy, Conservation

Front

What is the relationship between the speed of an object and its kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

How is work defined in physics?

Back

Work is defined as the transfer of energy that occurs when a force is applied to an object and the object moves.

Front

What is the formula for calculating gravitational potential energy?

Back

Gravitational potential energy (PE) is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the value of gravitational acceleration (g) on Earth?

Back

The value of gravitational acceleration (g) on Earth is approximately 9.8 m/s².

Front

What is the unit of measurement for work?

Back

The unit used to measure work is the Joule (J).

Front

What happens to energy when work is done on an object?

Back

When work is done, there is always a transfer of energy.

Front

What is kinetic energy and how is it calculated?

Back

Kinetic energy (KE) is the energy of an object due to its motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

How does height affect gravitational potential energy?

Back

Gravitational potential energy increases with height; the higher an object is, the more potential energy it has.

Front

What is the difference between work and energy?

Back

Work is the process of energy transfer, while energy is the capacity to do work.
