Direction refers to the path or orientation of an object's motion, while velocity is the rate of change of an object's position with respect to time. In other words, direction tells us where an object is moving, while velocity tells us how fast it is moving in that direction.
The direction of a ball is determined by the angle at which it is thrown or kicked, as well as any external forces acting on it such as wind or gravity. It can also be affected by collisions with other objects or surfaces.
The velocity of a ball can be affected by the initial force applied to it, the mass of the ball, air resistance, and any external forces such as gravity or friction. The surface on which the ball is rolling or bouncing can also impact its velocity.
Impulse is the change in momentum of an object. In the case of a ball, it is the force applied to the ball over a period of time, which causes a change in its velocity. This can be seen when a ball is struck or kicked, as the force applied to it increases its momentum and causes it to move in a certain direction.
The direction and velocity of a ball can be measured using tools such as a radar gun or a video analysis system. The impulse of a ball can be calculated by measuring the change in its momentum before and after a collision or impact. This can be done using the formula: force x time = change in momentum.
