If an object has kinetic energy, what must it be doing?

Answer:

It has to be moving in order for it to be kinetic energy and potential energy is when is not moving.

Answer:

The Object Must Be Moving!

Explanation:

Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed.

A ball is thrown up into the air. Describe the work done on the ball and the energy transformations that take place
between the time the ball is released and the time it reaches its maximum height.

What landform is created when an oceanic plate and a continental plate converge?

NASA plans to launch a new satellite to orbit the Earth. As the satellite is launched the thrust of the hot exhaust gas is pushed through the rocket nozzle and is accelerated toward the rear of the rocket. In turn, the rocket engine is then lifted off of the ground. According to Newton's 3rd law of motion, which statement below is true of the forces involved?
A The downward force exerted by the exhaust on the engine is greater.
B The magnitude of both forces is equal to zero acting in opposite directions.
C Both forces are equal in magnitude, but opposite in direction.
D The upward force exerted by the engine on the exhaust is greater.

Roxanne is an expert at blowing bubbles with bubble gum. She discovered that her bubbles were bigger if she stood facing the Sun when she blew them. At lunch she told her three best friends about her discovery and after school they all tried it. No one else was able to blow bigger bubbles when they faced toward the Sun. Which of the following would be best for Roxanne to do next? A. She should prove she is right by blowing bubbles while her friends are watching.
B. She should give them each bigger pieces of bubble gum and try it one more time.
C. She should think about what else she is doing that might have made the bubbles bigger.
D. She should ask her friends to try it again and concentrate harder when they face the Sun.
