Eighth Grade Science Homework for the Week of
10/31-11/4
Monday- Tuesday 10/31-11/1
Remember:
· Work is measured in Joules (J) and is
equal to the force(N) times distance(m).
· To find force (N) when given a mass
(kg) to be lifted, multiply the mass (kg) times the acceleration of gravity
(9.8 m/s2.)
· Power is work divided by time and is
measured in Watts. 10 Joules of work done in 2 seconds requires 5 Watts.
Answer the following questions:
1.
How
much work is done when a forklift lifts a 200kg crate to a height of 10 meters?
2.
If
this work is done is 2 seconds, how much power was used?
3.
If
your mass is 55 kg and you have to climb a flight of stairs which is 4 meters
high, how much work is required?
4.
If
you sprint up the stairs in just 2 seconds, how many Watts of Power did you
produce?
5.
What
if you walked slowly and it took you 60 seconds to climb the stairs? How much
power is required?
6.
If
you have to lift a big rock (500kg) into the bed of a pick-up truck 1.5 meters
high, how much work is required to do this job?
Wednesday 11/2
Review your class notes on work, power and simple machines and levers. Refer to
the Work
Power and Simple Machines Powerpoint if you get stuck. Answer the following
questions:
1.
You
have to lift a big rock (500kg) into the bed of a pick-up truck 1.5 meters
high. If you used a 1st class lever whose effort arm was twice as
long as the resistance arm, how much force would be required to lift the
rock?
2.
What
distance would the effort force be applied over?
3.
Draw
a diagram of the lever and rock and remember that without friction, work in =
work out. Show input force and distance and output force and distance. Remember
both sides of the machine should have the same values for work! Remember, you
have to lift the rock 1.5 meters, so use that value for your output distance.
