A 20 N object is pushed 3 meters. Calculate the amount of work performed.
F = 20 N
d = 3 m

What is the equation for Work?
1. W = Fd
2. F = ma
3. S = D/T
4. a = S/D
5. D = m/v
6. P = W/t
7. KE = (1/2)mv²
A 20 N object is pushed 3 meters. Calculate the amount of work performed.
F = 20 N
d = 3 m

Equation: W = Fd

Which of the following is correct?
1. W = (20 N) x (3 m)
2. W = 20 N ÷ 3 m
3. W = 20 N + 3 m
4. W = 20 N - 3 m
A 20 N object is pushed 3 meters. Calculate the amount of work performed.
F = 20 N
d = 3 m

Equation: W = Fd
W = 20 N x 3 m

So W =
1. 60 J
2. 60 Nm
3. 60 m
4. 60 kg m/s

5. t (Time)
6. d (Distance)
7. a (acceleration)
8. W (work)
