SAQ 1 Question:
1. List as many different types of energy as you can. Try to
think of an example of each type of energy that you come
up with.
2.
a) A 20 N crate is lifted 5 m from the floor onto a shelf at a
speed of 15ms-1. How much kinetic energy is used to lift
the crate? Assume that the force of gravity is 10ms-2
b) How much potential energy does the 20 N crate have
whilst sat on the self?
3.
a) A 30N force is used to pull a block along a friction-free
surface for 10m. How much work has been done?
b) A travel kettle has a power of 1kW. It boils a cup of
water in 80 seconds. How much energy is transferred?
c) A person whose mass is 80kg runs up two flights of
stairs, totalling 20m high, in 10 seconds. What is the
average power of the person?
4. Draw a Sankey diagram to represent a filament lamp
where only 10% of the electrical energy is converted into
light energy.
Your answer:
1. Gravitational potential energy – holding a box off the
ground. Chemical energy – ATP in the body. Kinetic energy –
a moving car. Elastic potential energy – a stretched rubber
band. Electrical – energy that travels through a cable wire to
power a TV. Between 2 charged particles. Thermal energy –
heat in a toaster. Light energy – when light is created through
a torch. Sound energy – energy that is produced from
speakers. Magnetic – Earth. Nuclear – Nuclear power plant.
