1. Change in motion: A force can cause an object to start moving if it was at rest, stop moving if it was in motion, or change its direction of motion. This is described by Newton's first law of motion (inertia) and second law of motion (force causes acceleration).
2. Change in shape: A force can deform an object, changing its shape. This is especially true for flexible materials like rubber bands or clay. Think of squeezing a ball – you are applying a force that changes its shape.
3. Change in speed: A force can cause an object to speed up (accelerate) or slow down (decelerate). This is directly related to Newton's second law of motion, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
