a. There is no gravity.

b. You can't defy gravity without going to another planet.

C. Gravitational force exists every place where there are two objects.

d. Nothing has enough force to resist gravity.

Define the theory of relativity?

Which of the following is true of the inner core of the earth? A. It is the consistency of asphalt. B. The average temperature is 4000 degrees. C. It is so hot that the elements vibrate in place. D.

In order to increase the amount of work done, we need to: A. decrease the force applied to an object. B. decrease the time to do the work. C. increase the time to do the work. D. increase the force applied to the object.

An object is released from rest near and above Earth's surface from a distance of 10m. After applying the appropriate kinematic equation, a student predicts that it will take 1.43s for the object to reach the ground with a speed of 14.3m/s.
