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.

Question 3When you stand and remain motionless on a bathroom scale, what force is the scale exerting on your feet?1 pointAn upward support force greater than your weight, to keep you from falling.An upward support force equal in amount to your weight.An upward support force less than your weight, to allow the scale to read your weight.Zero force, so that the scale can read your weight.

Consider what happens when you jump up in the air. Which of the following is the most accurate statement?Group of answer choicesIt is the upward force exerted by the ground that pushes you up, but this force cannot exceed your weight.Since the ground is stationary, it cannot exert the upward force necessary to propel you into the air. Instead, it is the internal forces of your muscles acting on your body itself that propels your body into the air.When you push down on the earth with a force greater than your weight, the earth will push back with the same magnitude force and thus propel you into the air.When you jump up the earth exerts a force F1 on you and you exert a force F2 on the earth. You go up because F1 > F2.You are able to spring up because the earth exerts a force upward on you that is greater than the downward force you exert on the earth.

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.

You are standing up straight on a mini-trampoline with your upper limbs stretched out horizontally in front of you, holding 2.5-kg weights in each hand. Maintaining this position, you attempt to bounce up in the air, rotate 180 degrees around your longitudinal axis and land back on the trampoline. It is difficult, although possible, to complete this movement because:Question 8Select one:a.more mass is distributed away from the axis of rotation in this position which increases your linear inertia making it difficult to rotateb.you have to generate more angular momentum after you leave the mini-trampoline and while you are in the air so that you can obtain sufficient angular velocity to complete the turnc.you have to use gravity as the external force to assist you to rotate around your longitudinal axis and this increased linear inertia makes it difficult to rotated.none of the statements are true

f you place a weight scale under your feet while you are in a lift in free fall what your weight would be?
