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.

According to Newton's law of universal gravitation, which of the following changes would increase the gravitational force between two massive objects most?

A halving one of the masses
B halving the distance between them
C doubling one of the masses
D doubling the distance between them

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.

Write a scientific explanation to answer the following question:

How do particles in matter change when a substance becomes hotter, cools down, or changes state?

Be sure to include the three main points of a scientific explanation:

A scientific claim
Evidence to support the claim
Reasoning that connects the evidence to the claim

Students working together to understand information is best described as
1. independent study.
2. home schooling.
2. collaborative learning.
4. secondary education.

1. What evidence of a PHYSICAL change would you find in a holiday feast or over Thanksgiving break? For example, describe a change in mass, volume, state or shape where the original substance has not been chemically changed. Be specific and give details.

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.
