50 J
Calculate the kinetic energy of a 2 kg object moving at 3 m/s.
6 Joules
12 Joules
9 Joules
3 Joules
If a 5 kg object is lifted to a height of 10 m, what is its potential energy?
490.5 J
2450 J
50 J
1000 J
How much power is used if 100 J of work is done in 5 seconds?
20 W
15 W
25 W
50 W
Convert 1 Joule to Newton-meters.
1 Joule = 2 Newton-meters
1 Joule = 10 Newton-meters
1 Joule = 1 Newton-meter
1 Joule = 0.5 Newton-meters
If a car does 2000 J of work in 10 seconds, what is its power output?
300 W
150 W
250 W
200 W
What is the formula for calculating work?
Work = Force - Distance
Work = Force × Distance × cos(θ)
Work = Force / Distance
Work = Force + Distance

50 J
25 J
75 J
0 J
What unit is used to measure power?
ohm
joule
watt
volt
If a machine has a power rating of 1500 W, how much work can it do in 1 minute?
30000 J
90000 J
60000 J
120000 J
