Answer:
For an object to move, there must be a force. A force is a push or pull that causes an object to move, change direction, change speed, or stop. Without a force, an object that is moving will continue to move and an object at rest will remain at rest.
Explanation:
2. When the child is pushed in the toy car, he increases speed. Does he accelerate as he is being pushed?

A. No combustion
B. Makes ionic bonds
C. Product of mixing acids and bases
D. Solid does not conduct electricity
Answer: it was in the lesson, the answer is it is solid and does not conduct electricity
Explanation:
Physical Properties Chemical Properties
White cubic crystals Do not undergo combustion
Odorless, salty taste Make ionic bonds easily
As solids, they do not conduct electricity The product of mixing acids and bases
Where does the force come from when a bumper car changes speed?
Answer:
Newton's second law
Explanation:
The rate of change of momentum of an object is equal to the net force acting on it. When bumper cars collide they push on each other. These pushes cause the momentum of each car to change.

How were the novae on Venus similar to the landforms in Gerya’s computer model?
Answer:
Explanation:
The model results matched the novae on Venus. This provided evidence that Gerya's idea that a thinner crust and higher surface temperature might allow melted rock to push up toward the surface, forming novae.

List three examples of where potential energy is transformed to kinetic energy in the Rube Goldberg Machine simulation. Fully explain the energy transformations using complete sentences. (Example: The ball has potential energy when it sits on the shelf that transforms to kinetic energy when it falls to the ground.)
DO NOT COPY AND PAST THE ANSWER FROM 2018 AND IF YOU HAVE A QUSTOIN ABOUT IT ASK UNDER THE QUSTION DO NOT ANSWER IT TO ASK A QUSTION
Answer:
1. The ball will have potential energy at the top of the mountain, when the ball falls the ball will have kinetic energy .
2. The roller coaster has potential energy when stopped on the very top, therefore it releases kinetic energy when it falls down the rollercoaster.
3. The car on the hill had potential energy weather when it went down it had kinetic energy.

ok lol
im bored
Explanation:
You are looking at two samples of iron. One sample is very small and came from the red soil on the planet Mars. The other sample is very large and came from Earth's core. True or False, these two samples contain different atoms
