Which requires more work – a person walking up stairs or a person running up stairs?
walking
running
they require equal work
no work is required for either because the movement is vertical
Which requires more power – a person walking up stairs or a person running up stairs?
walking
running
they require equal power output
no power is required at all

potential energy
momentum
work
all of these
W = F x d It took 500 N of Force to push a car 4 meters. How much work was done?
(a)
W = F x d Jim exerted a force of 9000 N on a stalled car, but was unable to move it. How much work did he do?
(a)
d = W ÷F 450 Joules of work are needed to push a box up a ramp. The force needed to push the box up the ramp is 15 N. How far up the ramp was the box pushed?
(a)
t = W ÷P How long does it take to do 1350 J of work with 15 watts of power?
(a)
P = W ÷t If 11,340 Joules of work is used over the span of 42 seconds, how much Power did it generate?
(a)
