Answer:
Concept :
A projectile is an item that is launched into the air and then moves exclusively in response to the acceleration of gravity. The trajectory of the item is referred to as the projectile's route. There is no horizontal movement in a one-dimensional projectile motion described by one-dimensional kinematics. This section examines the velocity of two-dimensional projectiles, such as a football or other item with minimal air resistance.
Explanation:
- According to Isaac Newton's first rule of motion, unless an outside force acts upon it, an object at rest tends to stay at rest whereas an object in motion tends to stay in motion.
- It would seem that nothing would go in the way of a basketball player's shot. However, the ball is subject to a number of external influences.
- The ball would keep moving in its current direction if these forces weren't there.
- The ball is first pulled down to earth by gravity. To determine the proper line of trajectory so the ball arcs into the basket, the athlete must calculate the force of gravity using the ball's weight.
- The answer is Motion of a basketball thrown to another member of the team.
