Question

question 15
a girl throws a basketball to try to score a winning goal.
determine which type of force gets the ball moving.
gravity
applied force
elastic force
air resistance
im not sure

question 16
identify two other forces acting on the ball as it sails through the air.
gravity
applied force
elastic force
air resistance
im not sure

Explanation:

• Question 15: An applied force is a force that is applied to an object by a person or another object. When the girl throws the basketball, she is applying a force to the ball, which causes it to move. Gravity is a force that acts on all objects with mass, pulling them towards the center of the Earth. While gravity does act on the basketball, it is not the force that gets the ball moving. Elastic force is a force that is exerted by an object when it is stretched or compressed. Air resistance is a force that opposes the motion of an object through the air. Neither of these forces are responsible for getting the ball moving.
• Question 16: Gravity is a force that acts on all objects with mass, pulling them towards the center of the Earth. As the basketball sails through the air, gravity is pulling it downwards. Air resistance is a force that opposes the motion of an object through the air. As the basketball moves through the air, air resistance is acting on it, slowing it down. Applied force is the force that was used to throw the ball, but once the ball is in the air, the applied force is no longer acting on it. Elastic force is a force that is exerted by an object when it is stretched or compressed. There is no elastic force acting on the basketball as it sails through the air.

Answer:

• Question 15: Applied force
• Question 16: Gravity, Air resistance
