Motion & Energy
What do we call the energy an object has because it is moving?
Kinetic Energy
What gets it's energy from food?
Humans/kids/ students/ Parents
Energy
The Ability to do work
Sound Energy
Deals with vibrations/ sound waves/
Buffer Stop
A device that helps stop the train
Train stopper
True or False: Energy is the ability to do work.
True
What get's its energy from gas?
Car
Source Energy
Where energy comes from, like the sun, wind, or food.
Heat Energy
Also known as - Thermal/Heat (warmth)
What does Speed equal
Distance / Time
The faster an object moves, does it have
(A) less energy,
(B) more energy,
(C) the same energy
B. More Energy
What gets it's energy from sunlight?
Plants
Potential
Electrical Energy/ Mechanical
Electrical (moving electricity in wires)
Mechanical (moving objects)
What is Speed?
Speed is the rate at which an object changes its position.
When two objects collide and one changes direction, which quantity (motion or stored energy) likely changed for that object?
Motion changed; kinetic energy changed
Where does television get it's energy from
Electricity
Collision
A collision happens when two objects hit each other
Light Energy
Light (from the sun or bulbs)
Does and Energy and Speed have to deal with each other
Yes the more Speed the More energy. The Less Speed, the Less Energy it has
Explain how a change in speed and a change in direction show that energy has been transferred during a collision. (Short answer for students)
A change in speed and/or direction shows energy was transferred from one object to another during the collision.
Can energy be destroyed yes or no and why?
No it can only be transferred
Kinetic Energy
Chemical Energy
Chemical (stored in food, batteries, fuel)
Train that run on Magnets are?
Maglev Trains
