Force of Motion(Gravity/Friction)
2 Parts:
Question 1: What is friction?
Smooth surface = _____ friction
Rough surface = _____ friction
Friction is a type of force that acts when two forces act together to stop or slow down a object.
LESS friction
MORE friction
What type of energy can you hear?
Sound energy
What happens when energy moves from one object to another?
Energy Transfer
What is a conductor?
A material that allows energy to pass through easily
COME ON THROUGH
What provides energy is a simple battery powered circuit?
The battery
Give me a example of something gravity is PULLING on?
Ex: People, Desk, Rocks, Chairs, etc
What kind of energy helps us see(also comes from the sun)?
Light energy
When you rub your hands together, what type of energy does friction produce?
Thermal Energy
Is a metal spoon a conductor or an insulator?
Conductor
⭐ What must a circuit have for electricity to flow continuously?
A complete closed path
⭐ What force slows objects down when two surfaces rub together?
Friction
What type of energy does a moving bicycle have?
Mechanical Energy
When a lamp is turned on, what energy changes into light energy?
(What energy do you have first before light?)
Electrical energy
Is rubber a conductor or insulator of electricity?
What happens when a switch is open in a circuit?
The flow of electricity stops
Why is it harder to slide a box across carpet than across a smooth floor?
Carpet creates more friction
⭐ Name all 6 types of energies(Think M.E.L.T.S and what makes things melt)
Mechcanical
Electrical
Light
Thermal
Sound
Solar
⭐ When you turn on a flashlight, what happens to the electrical energy from the battery?
It is transferred into light energy and thermal(heat energy)
⭐ Why are the handles of some cooking pans made of plastic?
Plastic is an insulator that slows transfer of heat
