Elastic Potential Energy Formula

What is the formula for calculating the elastic potential energy stored in a spring?

• Mass of the object attached to the spring

• Acceleration due to gravity

• Displacement of the spring from its equilibrium position

• Spring constant, a measure of the spring's stiffness

Which of the following units is used to measure elastic potential energy?

• Newtons (N)

• Joules (J)

• Meters (m)

• Kilograms (kg)

• Time

• Velocity

• Displacement from the equilibrium position

• Mass of the object attached to the spring

Which of the following is a real-life example of elastic potential energy?

• A car moving down a hill

• Water stored behind a dam

• A compressed spring in a toy gun before it is released

• A ball being thrown into the air

What happens to the elastic potential energy stored in a spring as it is compressed or stretched further from its equilibrium position?

• It remains constant

• It decreases

• It increases

• It first increases, then decreases

Which of the following factors does NOT affect the amount of elastic potential energy stored in a spring?

• The material of the spring

• The mass of the object attached to the spring

What is the potential energy stored in a spring with a spring constant of 200 N/m that has been compressed 0.5 meters from its equilibrium position?

• 25 Joules

• 50 Joules

• 100 Joules
