- F (Force)
- m (mass)
- v (velocity)
- s (Speed)
- t (Time)
- d (Distance)
- a (acceleration)
- W (work)
A 20 N object is pushed 3 meters. Calculate the amount of work performed.
F = 20 N
What does 3 meters mean?
- F (Force)
- m (mass)
- v (velocity)
- s (Speed)
- t (Time)
- d (Distance)
- a (acceleration)
- W (work)
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?
- W = Fd
- F = ma
- S = D/T
- a = S/D
- D = m/v
- P = W/t
- 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?
- W = (20 N) x (3 m)
- W = 20 N ÷ 3 m
- W = 20 N + 3 m
- 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 =
- 60 J
- 60 Nm
- 60 m
- 60 kg m/s
How much work is needed to lift a 500 N elevator up 4 meters?
What does 500 N mean?
- F (Force)
- m (mass)
- v (velocity)
- s (Speed)
- t (Time)
- d (Distance)
- a (acceleration)
- W (work)
How much work is needed to lift a 500 N elevator up 4 meters?
F = 500 N
What does 4 meters mean?
- F (Force)
- m (mass)
- v (velocity)
- s (Speed)
- t (Time)
- d (Distance)
- a (acceleration)
- W (work)
How much work is needed to lift a 500 N elevator up 4 meters?
F = 500 N
d = 4 meters
What is the equation for Work?
- W = Fd
- F = ma
- S = D/T
- a = S/D
- D = m/v
- P = W/t
- KE = (1/2)mv2
How much work is needed to lift a 500 N elevator up 4 meters?
F = 500 N
d = 4 meters
Equation: W = Fd
Which of the following is correct?
- W = (500 N) x (4 m)
- W = 500 N ÷ 4 m
- W = 500 N + 4 m
- W = 500 N - 4 m
How much work is needed to lift a 500 N elevator up 4 meters?
F = 500 N
d = 4 meters
Equation: W = Fd
W = 500N x 4m
So W =
- 2000 J
- 2000 m
- 2000 Nm
- 2000 kg
