Intro to Energy
What is mechanics
the study of motion
Energy that is being stored is called?
What is the rate and speed in which something moves?
People who build and design building, bridges and dams?
What energy is most visible, easy measure and test.
Kinetic Energy is?
What is energy that is being used.
When a chemical reaction takes place and energy is released.
What is Chemical reaction ( food, fire)
Scientists have determined that changes in momentum have to be equal. We call this?
What is the Law of Conservation
A push or a pull
The study of non-living things is called?
This energy has the potential to pull things down.
Kinetic and Potential energy that is converted by using charged particles.
What is electrical energy ( lights, and batteries)
movement in a specific direction is called?
What is Momentum
The amount of tension a material can withstand
What is Tensile Strength
What is Energy.
One example from class of something that has both potential and kinetic energy.
What is a pendulum/ Newtons Cradle, roller coaster, our rubber band target game.
The telephone is an example of what type of energy?
What is sound energy
You have a tour bus, and a motorcycle, both are traveling at the same velocity, which one has more momentum?
The bus because it has more mass.
What is a key factor in if something floats?
What is Density
What type of energy is used when you swing a bat in baseball?
What is Mechanical Energy
In class we used toy cars to demonstrate energy, why did the car stop?
It had no more usable energy. ( Law of Conservation of Energy the energy was converted to something else)
These two qualities affect momentum.
What is mass and velocity
These bridges are a good example of a force that is less visible than a opening or closing a door.
