A weightlifter lifts two 300 newton weights 1.5 meters off the ground. How much work has he done? a) 100N b) 100 J c) 100 m/s d) 100 W
What is needed to calculate work?
Work is done on an object when the object moves in ANY direction in which the force is applied (T/F).
The unit of power is the...
A weightlifter lifts two 300 newton weights 1.5 meters off the ground. How much work has he done?
You do 90 joules of work in 30 seconds. How much power have you generated?
The more POWER you use to move an object, the more work you do.
Power is the RATE at which work is done.
If you lift a box from the floor to a height of 1m and then carry the for for 10m, you do work only when you CARRY the box (T/F)
You move a 12-newton box up a 6-meter ramp. In order to find out how much power you created, what would you need to know?
A kid applies a force of 70 N to a ball over 1.1 meters. How much work did he do on the ball?
It measures how much effort is applied over a certain distance
Work divided by time equals...
The FARTHER you move an object, the more work you do (T/F)
You move an 8-newton weight five meters in 4 seconds. How much power have you generated?
