Energy Basics
What is energy?
The ability to make things move or change.
True or false: Energy can cause change?
True
A soccer ball rolls across the field. What type of energy does it have?
Kinetic
A person pulls back a bow and releases an arrow. Describe the energy change.
Pulling the bow stores potential energy. When its released, it changes into the arrows kinetic energy.
When and where do we put our homework?
In the bins that are in the back of the room on top of the computer cart.
Name the two main types of energy we have studied.
Kinetic energy and Potential energy.
What type of energy does a moving bicycle have?
Kinetic
Which has more kinetic energy: a slowly rolling ball or the same ball moving quickly? Explain.
The quickly moving ball because greater speed means more kinetic energy.
Why does riding a bicycle require and use energy?
The rider uses energy they received from food to move the bike with
At what voice level do we enter the room?
ZERO!!!!!!!!!
What kind of energy does a moving object have?
Kinetic energy
Name one way you use energy every day.
running, walking, cooking, or playing
Two objects move at the same speed. One has more mass. Which object has more kinetic energy?
The object with more mass.
A roller coaster travels down a hill. Describe how its potential and kinetic energy change.
As the roller coaster travels downhill, its potential energy decreases and its kinetic energy increases.
When can you ask to go to the bathroom?
The second half of the hour and not when you are first entering the class. That is a Automatic no.
What kind of energy is stored and ready to be used?
Potential energy.
What happens to kinetic energy when an object speeds up?
It increases
Why is it usually easier to gather evidence that an object has kinetic energy than potential energy?
Motion can be observed or measured. Potential energy is stored and may not be visible.
True or false : Energy can be created from nothing?
false, energy must come from another source
What days do we have science homework?
Tuesday and Thursday
Give one example of energy causing a change.
moving an object , heating something, producing light, or changing an objects shape.
What was the bills score last night?
36~31
A bicycle speeds up. What happens to its kinetic energy? Use evidence in your answer.
The kinetic energy increases. The bikes increased speed is evidence that it has more kinetic energy.
What is a energy source?
Something that provides energy
When you hear me starting to count down from 5 or you hear the chime, what should you do?
Stop talking and start to track me immediately.
