An object is raised above the ground gaining a certain amount of potential energy. if the same object is raised twice as high, it gains:

Blocks with masses of 3.0 kg, 4.0 kg, and 5.0 kg are lined up in a row on a frictionless table. All three are pushed forward by a 13 N force applied to the 3.0 kg block. How much force does the 4.0 kg block exert on the 5.0 kg block?

How are mass and weight related? a) Mass is weight multiplied by gravity b) Weight is an intrinsic property, mass is not c) Weight is mass multiplied by gravity d) Weight and mass are not related

22.0-kg child is riding a playground merry-go-round that is rotating at 40.0 rev/min. What centripetal force is exerted if he is 1.25 m from its center? (b) What centripetal force is exerted if the merry-go-round rotates at 3.00 rev/min and he is 8.

An object has 90,000 J of kinetic energy and is moving at 12 m/s. What is the objects mass?

What does thermal energy mean?

A yummy glazed doughnut is shown above. 1) where is the center of mass of this fantastic culinary delight? in the center of the hole. somewhere inside the solid part of the doughnut the center of mass is not defined in cases where mass is missing.

10. Explain the difference between the short-term effects of concussions and some of the long-term effects that scientists are recently discovering.

Like the polar bear, the walrus is a strong swimmer, although it does not have the same endurance. For short periods of time, a walrus can swim at an average speed of 9.7 m/s. How far would a walrus swim at this speed in 3.4 minutes?

How did Einstein's and Newton's theories differ in terms of explaining the cause of gravity?
