What is force?
A push or a pull force.

What are 4 types of natural resources?
Sun, soil, air, and water.
Other acceptable answers: minerals, rocks, plants, animals
200
Recycling, reducing, and reusing are important ways to help people to ______?
Save natural resources.
200
If a surface of a track is smooth, will the car experience more friction or less friction? Explain why.
When a surface is smooth, there is less friction force acting upon the car. The car is able to slide across the surface more easily than a bumpy surface.
200
What is a slope?
A rising or falling surface.
200
Name 2 examples of potential energy?
a charged battery, stretched rubber band, a car at the top of a hill, etc
300
Give 3 examples of ways people can conserve water?
Turn off water pipes when not in use, don't take long showers, do laundry when you have a big pile of clothes to wash rather than washing everyday
Other acceptable answers: collect rainwater, use a broom rather than water to clean off sidewalks and outdoor areas, turning off the water while brushing teeth.
300
If I want to have the most kinetic energy, where should I be on the slide?
At the very top or beginning of the slide. The most kinetic energy would be at the highest position for potential energy.
300
What is a landfill?
A place where trash gets taken to. The trash is either buried or burned.
300
What is the relationship between height, speed, and distance?
The higher the object on a slope or ramp, the faster the object can move. It will also go a farther distance after it slides off of a ramp or slope.
400
Why should people learn and practice conserving water?
Conserving water helps to limit the amount of water being used. Although Earth is made up of 70% of water, only a small percentage is freshwater that is available to people. People are using these natural resources faster than it's being produced.
400
Potential energy turns into ________ when the object is in motion.
Kinetic energy.
400
What is friction?
A contact force that opposes the motion of an objec
400
What is the force that keeps everything down towards the ground?
Gravity.

How do you think water pollution affects the sea animals in the ocean?
Sea animals are being trapped and eating materials such as plastic which is making their habitat unsafe. The water is being contaminated by plastic, garbage, toxic chemicals and other pollutants causing sea animals to become sick and potentially die.

If I want to make a marble roll down the ramp faster, what should I do to the ramp?
Make the ramp steeper.
500
What is energy?
The ability to do work.

If a tall and short person were competing in a skiing race down a slope, who is going to win?
The tall person. They have the most potential energy at the start, therefore they will have the most kinetic energy and go a farther distance.
