If an object accelerates toward earth at 9.8 m/s^2 at the surface regardless of mass and an object accelerates toward the moon at 1.622 m/s^2 at the surface regardless of mass then how is their a gravitational ...

The average current in a resistor in an ac circuit is zero. Explain why the average power delivered to a resistor is not zero.

A rocket generates a net force (F) of 2,050,000 newtons, and the rocket’s mass (m) is 40,000 kilograms. Use the formula F = ma to find the acceleration (a) achieved. A. 51.25 meters/second^2 B. 51.125 meters/second^2 C. 42.25 meters/second^2

Is there less gravity at the north pole?

Are most collisions elastic or inelastic?

Particle A of mass 500g is moving with a constant velocity of 12m s^-1 towards particle B of mass 1.5kg which is initially at rest. After collision, particle A comes to a rest and particle B moves ...

I just read that in an impact some energy can be turned into heat instead of transferring momentum. So how fast would the ice cube impact need to be for them to turn into ...

Then , he grabs harder on rope, increasing the tension on the rope. As soon as the upward tension in the rope becomes equal to his weight , Will the boy stop OR will the boy continues down ...

Shouldn’t they stop with time? I mean go ahead and shake a bottle of water, it will shake and it will eventually stop, unless you shake it again. What makes the sea water move so much? Why doesn’t ...
