Different Forms of Energy
What is potential energy?
Stored Energy
Who were the two scientists we looked at, at the start of the term?
Sir Issac Newton and Albert Einstein
What is the energy efficiency formula?
useful energy output/total energy input x100
How is energy transferred for a weightlifter?
When a weightlifter lifts the weights into the air, they are transferring energy from their body to the weights in the form of additional gravitational potential energy
What is the powerhouse of the cell?
Mitochondria
What is Kinetic Energy?
The energy of motion
What is the energy stored in batteries is transformed into light when a torch is switched on?
Chemical
What are the three components of an electrical circuit?
- power supply
- a load
- a conducting path
What is the energy transfer of a golfer hitting the ball?
Energy transfers from your muscles into the club and finally into the ball in a golf swing
What are prokaryotes?
Organisms that are made up of cells that do not contain membrane-bound organelles such as a nucleus
What is the law of conservation?
Energy cannot be either created or destroyed
What is the energy conversions that occur when bouncing on a trampoline?
GPE - KE - Elastic potential energy - KE - GPE
When a bicycle skids to a stop, its kinetic energy is mostly transformed into..
Heat and Sound
What game is based off a Rube Goldberg Machine?
Mouse Trap
What are eukaryotes?
are made up of cells that contain membrane-bound organelles such as a nucleus
What are the 6 types of potential energy?
Gravitational, Elastic, Chemical, Electrical, Magnetic, Nuclear
What are the energy outputs of the example on the board? There are three
Light, sound and heat
What is the method of fire drilling?
Rubbing a stick to create friction between the stick and the 'tinder' that causes a fire
What is the transfer of energy when performing a hit in tennis?
When a tennis ball hits the racquet strings, its kinetic energy is temporarily stored as elastic potential energy in the squashed ball and the racquet strings.
What are the 6 main kingdoms?
Animalia, Plantae, Fungi, Protista, Eubacteria and Archaebacteria.
What are the 5 types of kinetic energy? (30 points) - Give me an example of one (10 points)
Translational, Thermal, Radiant (Light), Sound, Electrical
What is a cool burning/cultural burning?
A traditional Aboriginal land management practice that reduces fire hazards, encourage new growth of culturally-significant species, and protect native wildlife already living on Country.
What is a load?
The load in an electric circuit is an energy converter (transducer).
What happens when the last ball is hit in a Newton's Cradle?
When this chain reaction reaches the last ball, the kinetic energy has no further ball to be transferred to. This ball then swings up with the same speed as the first ball and reaches the same height
What is cell division?
Allows cells to divide and produce new cells
