Kinetic and Potential energy calculations

Front

What is the formula for calculating potential energy?

Back

Potential Energy (PE) = mass (m) × gravitational acceleration (g) × height (h)

Front

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

Back

Joule (J)

Front

Calculate the potential energy of a 2,500 kg car on a hill 100 meters high.

Back

2,450,000 J

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 0.5 × mass (m) × velocity (v)²

Front

If an object has a mass of 3 kg and is moving at a speed of 4 m/s, what is its kinetic energy?

Back

24 Joules

Front

What factors affect gravitational potential energy?

Back

Gravitational potential energy depends on the height and mass of the object.

Front

What is the relationship between speed and kinetic energy?

Back

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

Front

How do we calculate work done?

Back

Work (W) = Force (F) × Distance (d) in the direction of the force.

Front

If a force of 10 N moves an object 5 meters, how much work is done?

Back

50 Joules
