Force= Mass multiplied by acceleration
Let's say I have a ball in my hand. It has no speed, due to the fact it is not moving. It's mass would be the ould be the same as it would be on the ground, mass never changes. So, if I threw the ball, the force would be equal to the mass of the ball, and the change of speed.
Acceleration means a change in speed. So to figure out the previous equation, we would say force is equal to mass, or weight, times the acceleration, or the change in speed.
Third Law of Motion
For every action, there is an opposite and equal reaction.
For every action, there is an opposite and equal reaction. This means that when an object hits another, the force of the object is the same as the force the other has when it bounces bounces back. Have you ever rolled two balls in opposite directions and they hit each other? The moment the touch, they both send forces against each other. They both roll back little, and the force one exerts, or lets out, is the same as the other ones, but in the opposite direction, and therefore equal and opposite
Forces always come in pairs like this. When you and your friend high-five, the force of the slap is distributed equally among the two of your hands.
