The formula for calculating the force of a ball-spring collision is F = kx, where F is the force, k is the spring constant, and x is the displacement of the spring.
The spring constant can be determined by dividing the force applied to the spring by the displacement of the spring. This can be done by measuring the change in length of the spring when a known force is applied.
Yes, the force of a ball-spring collision can be negative if the spring is compressed and the force is acting in the opposite direction of the displacement. This can happen if the ball is moving towards the spring with a greater velocity than the spring can expand.
The mass of the ball does not directly affect the force of the collision. However, a heavier ball may cause the spring to compress more, resulting in a larger displacement and therefore a greater force.
Yes, the force of a ball-spring collision can be greater than the initial force applied if the spring is compressed and then released, causing it to exert a larger force on the ball upon impact. This is known as the spring's "rebound effect".
