Question
work
work is the amount of force applied times the distance over which it is applied. in order for work to occur or happen... the object must move in the direction of the force applied.
work = force x distance w=f x d
solve:
- a force of 825 n is needed to push a car across a lot. two student push the car 35 m. how much work is done?
- you push against the wall for 3min with a force of 10 n. how much work is done? explain.
Step1: Identify the formula
The formula for work is \(W = f\times d\), where \(f\) is force and \(d\) is distance.
Step2: Solve for the first problem
Given \(f = 825\space N\) and \(d=35\space m\).
Substitute into the formula: \(W = 825\times35\)
\(W=28875\space J\) (Joules)
Step3: Analyze the second problem
The formula for work requires the object to move in the direction of the force. When pushing against a wall, the wall does not move (\(d = 0\space m\)).
Using \(W = f\times d\), with \(d = 0\), \(W=10\times0 = 0\space J\)

- \(28875\space J\)
- \(0\space J\) (Because the wall does not move, so \(d = 0\) and using the work formula \(W = f\times d\), the work done is \(0\))
