Force & Friction

Interactive Physics Presentation

What is Force?

Force is defined as an external cause that a body experiences as a result of interacting with another body. Whenever two objects interact, a force is exerted on each object.

PULL PUSH
A force that moves an object closer A force that moves an object away
Formula of Force: F = ma
Where, m is Mass of an object
a is the acceleration of the object.

Force Simulation: Football Kick

Adjust the force and mass to see how they affect the ball's motion according to Newton's Second Law (F=ma).

30 N
0.4 kg

Acceleration = 0 m/s²  

What is Friction?

Friction is a force that opposes the motion of the object to which it is applied.

Types of Friction

Static Friction

Prevents motion before it starts (µₛ)

Kinetic Friction

Acts when object is moving (µₖ)

Friction Simulation: Car on Different Surfaces

Change the friction coefficient to see how it affects the car's movement. Lower μ = slippery surface (ice) → car slides easily. Higher μ = rough surface (asphalt) → car struggles.

Relation Between Force & Friction

Friction depends on the normal force and the coefficient of friction between surfaces.

Friction Formula: f = μN
Where, μ = coefficient of friction
N = normal force

Interactive Force Playground
