Today well are going to explore simple machines/Newton laws
All about force and motion
Wheel and axle
The wheel and axle is one of six simple machines. The wheel and axle is generally considered to be a wheel attached to an axle so that these two parts rotate together in which a force is transferred from one to the other.
Example- A car is a wheel and axle
A pully is a simple machine. A simple machine makes work easy. A wheel with a grooved rim around which a cord passes. It acts to change the direction of a force applied to the cord and is chiefly used to raise heavy weights.
Newton's first law/Law of inertia
Newtons 2nd law of motion
The greater the force, the greater the speed.
