Class 11 Physics simulations · Motion in a Plane

Projectile with air resistance

Add linear air drag and compare the path with the ideal vacuum parabola.

Open the simulation

What to notice

Drag shortens the range and makes the descent steeper than the ascent.

Key relation

x = (u_x/k)(1 − e^(−kt)), y = (u_y/k + g/k²)(1 − e^(−kt)) − gt/k

Try this

With drag on, is 45° still the best launch angle?

What you can change

• Launch speed: 5 to 40 m/s
• Launch angle: 10 to 80 °
• Drag constant k: 0.02 to 1.5 1/s
