How do u calculate the work done on an object when you push it
To calculate the work done on an object when you push it, you can use the following formula:
Work (W) = Force (F) x Distance (d) x cos(theta)
where:
- Work (W) is the amount of work done on the object, typically measured in joules (J).
- Force (F) is the amount of force you apply to the object, typically measured in newtons (N).
- Distance (d) is the distance the object moves while you push it, typically measured in meters (m).
- cos(theta) is the cosine of the angle between the force and the direction of the displacement. If the force and displacement are in the same direction, theta = 0, and cos(0) = 1, meaning the work done is simply the product of the force and distance.
The formula states that the work done is equal to the force applied to an object multiplied by the distance the object moves, and the cosine of the angle between the force and the distance over which the object moves. If the force and distance are in the same direction, the work done is positive, and if they are in opposite directions, the work done is negative.
For example, if you apply a force of 10 N and push an object for 5 meters in the same direction as the force, the work done is:
W = 10 N * 5 m * cos(0) = 10 N * 5 m * 1 = 50 joules (J)
