Back

Potential Energy

Front

Calculate the gravitational potential energy of an object with a mass of 1000 kg at a height of 426 m. (Use g = 9.8 m/s²)

Back

4,260,000 J

Front

If an object has a mechanical energy (ME) of 1575 J and a potential energy (PE) of 1265 J, what is its kinetic energy (KE)?

Back

310 J

Front

What type of energy is elastic energy?

Back

Potential energy

Front

Kinetic energy is a subcategory of which type of energy?

Back

Mechanical energy

Front

Define Total Energy (TE) in physics.

Back

Total Energy is the sum of potential energy and kinetic energy in a system.

Front

What is the formula for calculating gravitational potential energy (PE)?

Back

PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the unit of energy in the International System of Units (SI)?

Back

Joule (J)

Front

Explain the difference between kinetic energy and potential energy.

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.

Front

What is the formula for kinetic energy (KE)?

Back

KE = 1/2 mv², where m is mass and v is velocity.
