3.5.1 Newton’s laws of motion

a.) Newton’s First Law - An object in motion remains in a state of motion unless a resultant force acts on it. If the resultant force is zero, this means: a stationary object stays stationary and a moving object continues to move at the same velocity.

Newton’s Second’s Law - F = ma

Newton’s Third Law -

Static friction on an inclined plane

F=μNF=\mu N

Where μ\mu is the coefficient of friction.

  • Static Friction is the friction when still.

  • Dynamic is the friction when moving.

Inertia is the tendency of an object to continue in its current state (at rest or in uniform motion)
