Class 11 Physics simulations · Work, Energy and Power

Spring launcher and energy transfer

Release a compressed spring and watch elastic potential energy turn into the cart’s kinetic energy.

Open the simulation

What to notice

The cart loses contact at the spring’s natural length and then travels at constant speed.

Key relation

½kx₀² = ½mv²

Try this

Double compression and compare launch speed with stored energy.

What you can change

• Spring stiffness: 20 to 100 N/m
• Cart mass: 0.5 to 3 kg
• Initial compression: 5 to 30 cm
