Energy Types
What type of energy does a moving object have?
Kinetic energy
What type of heat transfer occurs when touching a hot pan?
Conduction
If speed increases, what happens to kinetic energy?
It increases
Why does a ball slow down after rolling?
Friction
Which system shows energy transfer?
Any system where heat or motion changes
What type of energy is stored due to position (like height)?
Gravitational potential energy
Heat transfer through liquids and gases is called:
Convection
A graph shows increasing mass. What happens to kinetic energy?
It increases
What type of energy does a stretched rubber band have?
Elastic potential energy
Which BEST shows energy conservation?
Energy changes form but total stays same
A student releases objects from the same height and measures kinetic energy.
Which conclusion can be made?
Objects with greater mass have greater kinetic energy.
A student tests Styrofoam vs plastic.Which conclusion is correct?
Styrofoam is a better insulator
Which has more KE: fast small object or slow large object?
Depends on both mass and speed
Why does a stretched rubber band have energy?
Elastic potential energy
Which involve thermal energy transfer?
Name TWO types of potential energy.
Elastic, gravitational, chemical
Why does heat move from hot objects to cold ones?
Energy transfers to reach equilibrium
Interpret: Object A has double the speed of B.
Much greater KE (speed matters more)
Explain how energy changes when dropping a ball.
PE → KE
Explain how energy transfers in a cup of hot water cooling.
Heat moves to its surroundings
Explain how energy is conserved when a roller coaster moves.
PE → KE, total energy stays constant
Give an example of radiation and explain it.
Sun heating Earth (energy travels via waves)
Explain how data supports energy conservation.
Energy shifts forms but total remains same
Describe how thermal energy changes particle motion.
More heat = faster particles
A student designs a system where a ball rolls down a ramp.
Explain:
Top = potential,
bottom = kinetic,
