Impulse: catching an egg

Stop a falling object over a short or long time and compare the average force needed.

Open the simulation

What to notice

The impulse (area under F–t) is fixed by the change in momentum; stretching Δt lowers the peak force.

Key relation

F̄ = Δp / Δt = mv / Δt

Try this

Keep the speed fixed and make the stopping time ten times longer.

What you can change

• Mass: 0.05 to 1 kg
• Impact speed: 1 to 20 m/s
• Stopping time Δt: 0.005 to 0.5 s
