Forces & Motion — PhysicsSketch

Newton's 2nd Law — F = ma

Change force and mass. See how acceleration changes and the object moves.

Force (F) 10 N

Mass (m) 2 kg

Time (t) 3 s

F = ma → a = F/m = — m/s²

Friction — f = μN

Adjust the surface type and applied force. See if the block moves!

Applied Force 15 N

Mass 5 kg

Projectile Motion

Throw an object at any angle and speed. Watch the parabola form and calculate range, height, time.

Launch speed 20 m/s

Angle θ 45°

Gravity g 9.8 m/s²

R = v²sin(2θ)/g → Range = — m
