Newton’s 1st law:
Inertia, the tendency to continue in a given state.
Newton’s 2nd law:
The acceleration of an object is directly proportional to the net force, and inversely proportional to the mass. F=ma
Newton’s 3rd law:
For every force, there is an equal and opposite force.
The force need to accelerate 1kg at 1 m/s/s.
A reaction force pointing perpendicular to the surface.
When all the forces on an object balance out, or cancel out, the object has a net force of 0.
When an object is in equilibrium, and not moving, this is called static equilibrium.
An object moving at a constant velocity; no net force acting on it.
A force that always opposes motion.
Coefficient of friction:
The ratio between the frictional force and the normal force.
