Universal forces are the four fundamental forces existing in the universe. they are the strong nuclear force, the weak nuclear force, the electromagnetic force and the gravitational force. The strongest is the strong nuclear force and gravity is the weakest.

Force is defined as a push or a pole of an object that causes the object to slow down, speed up or stay in one place. Force generally causes an object to move. Friction and gravity are two types of forces that influence how objects move. The force of friction is the force that acts to slow an object down as you ride your bike through town and you encounter sand, your bike will slow down, because sand is a type of friction it is a force working against your legs as they push against the pedals. The force of gravity is pulling objects towards the Earth's center. When a ball is thrown in the air it slows down and falls back to the ground, that is because gravity pulls the ball back towards the earth. Everything on earth is influenced by the force of gravity push and pull forces are opposites meaning they move objects in different directions
