4.Question 4As a ball bounces on the floor, the floor exerts an upward support force on the ball. Can the amount of that upward support force on the ball be different from the ball's weight?1 pointYes. It can be greater than the ball's weight and it can be less than the ball's weight.Yes. It can be greater than the ball's weight. It cannot be less than the ball's weight.Yes. It can be less than the ball's weight. It cannot be greater than the ball's weight.No. It can only be equal in amount to the ball's weight.

Question 1You are in an ordinary room (both its floor and ceiling are horizontal). You throw a ball directly upward and it bounces off the ceiling. While the ball is touching the ceiling, in which direction is the ceiling's support force on the ball?1 pointThe ceiling's support force on the ball is directed downward.The ceiling's support force on the ball is directed upward.The ceiling's support force on the ball is directed downward while the ball is moving upward and is directed upward while the ball is moving downward.The ceiling's support force on the ball is directed upward while the ball is moving upward and is directed downward while the ball is moving downward

A ball of mass m is dropped from a height H above a level floor asshown in figure. After striking the ground it bounces off back andreaches up to height h.Based on above information, answer the following questions: H hm13. Change in momentum of the ball on striking is

A metal ball and a plastic ball each have a mass of 0.4 kg. Both balls undergo the same acceleration due to an applied force. Which of the following statements is correct?Group of answer choicesThe both balls experiences the same net forceThe metal ball is more dense and therefore requires a bigger force to accelerate itThere is not net force acting on either of the ballsThe plastic ball requires a bigger force to produce this acceleration

1. Michael is doing an experiment. He wants to drop a bowling ball and a stuffed bear out the window of a tall building. Under what conditions would they have the same acceleration? aIf they had the same mass.bIf they had the same weight.cIf there was no air resistance.dIf there was no gravitational force.

Question 1Which force is your weight? [The force that is your weight and not a force that is equal to your weight.]1 pointThe force you exert on a bathroom scale as you stand on that scale.The force that a bathroom scale exerts on you as you stand on that scale.The force you exert on a trampoline as you land on that trampoline after jumping high above the trampoline's surface.The force that causes you to accelerate downward when you are high above the surface of a trampoline.
