Force
Name at least 2 types of forces
Gravity, friction, and magnetic
This type of friction keeps an object at rest from moving, even when a force is applied.
static friction
Stored energy is...
energy waiting to be used; potential energy
This type of energy is stored in the bonds of atoms and molecules and released during chemical reactions.
chemical energy
This type of friction occurs when two solid surfaces slide over each other.
sliding friction
Which has more potential energy in this room: the clock, or Ms. Bussanich's coffee mug?
The clock
Which has more kinetic energy a fast ball thrown by Nick M. or an under hand pitch thrown by Ms. Bussanich?
Fast ball by Nick
When rubbing your hands together, mechanical energy is transformed into this type of energy that you can feel.
thermal (heat) energy
This friction occurs when an object moves through a gas or liquid, like air or water.
fluid friction
The _________ an object is the more potential energy it has.
higher or more mass
In a wind turbine, kinetic energy from wind is converted into this type of energy that can power homes.
electrical energy
This type of friction is typically the weakest and occurs when a wheel or ball moves across a surface.
rolling friction
Where would a child have more potential energy at the top of a slide or at the bottom?
top
This type of energy is carried by light and other electromagnetic waves
radiant (or light) energy
This is the reason why it’s harder to start pushing a heavy box than it is to keep it moving once it’s sliding.
static friction is greater than sliding friction
Name three different objects in the room with potential energy, then order them from most potential energy to least.
Example: clock, a book on a desk, and a pencil on the floor.
Energy stored inside the nucleus of an atom that can be released through fission or fusion is called this.
nuclear energy
