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.

2. When the child is pushed in the toy car, he increases speed. Does he accelerate as he is being pushed?
The woman riding the bike applies a force by pedaling the bike. However, she moves at a constant velocity. So her force must be balanced by another force. What force acts to balance her forward force?
Frictional Force is the one and only.
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.

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.

What element is this? Ignore my answer choice.
Answer:
Aluminum
Explanation:
It is your choice because only aluminum has 13 protons
Answer:
yea its aluminum the 13 element because of its 13 protons
