Final answer:
When investigating force when using a basketball, two important questions to consider are the forces acting on the basketball when it is stationary and when someone shoots it.
Step-by-step explanation:
When investigating force when using a basketball, there are two important questions to consider:
- Which forces are acting on the basketball when it is stationary, and are they balanced? When the basketball is stationary, the forces acting on it include the force of gravity pulling it downwards and the normal force exerted by the ground pushing it upwards.
- These two forces are balanced, resulting in the basketball staying in place.
- Which forces are acting on the basketball when someone shoots it, and are they balanced? When someone shoots the basketball, additional forces come into play.
- In addition to the force of gravity and the normal force, there is a force applied by the person shooting the ball and a force of friction exerted by the air.
- These forces may or may not be balanced depending on the circumstances, such as the angle and strength of the shot.
