The principle of equal and opposite forces, also known as Newton's third law of motion, states that for every action, there is an equal and opposite reaction. This means that when an object exerts a force on another object, the second object will exert an equal and opposite force back onto the first object.
When a ball is dropped onto a surface, it exerts a force on the surface due to its weight. According to the principle of equal and opposite forces, the surface will exert an equal and opposite force on the ball, causing it to bounce back up. This is because the surface resists the weight of the ball and pushes back with the same amount of force.
Several factors can affect the bounce of a ball, such as the material and texture of the surface it bounces on, the height from which it is dropped, and the composition and elasticity of the ball itself. These factors can either increase or decrease the force exerted on the ball and, therefore, affect its bounce.
A ball will bounce higher on a hard surface because it can exert more force on the ball due to its lower absorption of energy. A soft surface, on the other hand, will absorb more of the ball's energy, resulting in a lower bounce. This is because the harder surface can push back against the ball with a greater force, in accordance with the principle of equal and opposite forces.
The angle of impact, or the angle at which the ball hits the surface, can affect the direction of the ball's bounce. If the ball hits the surface at a 90-degree angle, it will bounce straight back up. However, if the angle of impact is less than 90 degrees, the ball will bounce at an angle away from the surface. This is due to the change in the direction of the equal and opposite forces acting on the ball.
