Experiements
Think about 2 cars on a ramp. One is at the top of the ramp and the other is half way down the ramp.
Which car has more energy- the one at the top or the one that is half way?
The car at the top.
True or False?
Energy is only measured by how fast something moves.
False
When the astroid hit Earth millions of years ago, what was was energy not transferred?
Light
Sound
Heat
Electricity
Motion
Electricity
Think about your ping pong ball experiment.
If Ms. Raverty dropped the ball 1 foot off the ground and then dropped the ball twice as high off the ground, which ball do you think bounced higher?
The ball that was dropped twice as high off the ground.
Where do humans get their energy from?
Food
Ms. Raverty is bouncing a ball. Where does the energy get transferred to?
The ground.
If two basketballs are rolling quickly towards each other, what will happen when they collide?
They will bounce off each other and roll away.
Can energy be 'used up'?
No, energy can only be transferred or given to something else.
Your Egg racer crashed! What is affected? (3)
The egg, the car, and the wall.
If a car is rolling down a ramp, at what point is the car's speed the fastest?
At the top, the middle, or the bottom of the ramp?
At the bottom of the ramp.
What are 5 different pieces of evidence that something has energy?
Heat, sound, light, electricity, and movement.
When we did our egg racer experiment, where did the car's energy get transferred to? List all the different places. (3)
The ground, the wall, and the air.
Think about your car with the ballon powering it. How could you have given your car more energy? Pick all that apply
Bigger wheels
More air in the balloon
Less air in ballon
Putting it on a ramp
having a longer tube for the air to go out of.
By blowing up the balloon more and putting it on top of a ramp
True or false?
Energy and Force are the same thing.
False
Energy and force are not the same thing. Force is a push or pull against something. Energy can be shown through light, sound, heat and others ways.
If a car drives through a muddy puddle, where does some of the energy get transferred to?
