An object is moved left to right horizontally 2 meters while a force of 3 Newtons to the left acts. No other forces act on the object. Draw a diagram of showing the displacement and the force and calculate the work done on the object in Joules.
work: force*distance=-3N*(+2)=-6joules
To draw a diagram showing the displacement and the force, we can use a simple coordinate system. Let's assume that the horizontal direction represents the left-right motion of the object, and the vertical direction represents the force.
Since the object is moved left to right horizontally, we can represent the displacement by drawing an arrow pointing from left to right, with a length of 2 meters.
Next, we need to represent the force of 3 Newtons to the left. We can draw an arrow pointing to the left, with a length representing the magnitude of the force, which is 3 Newtons.
The diagram should show the arrow representing the displacement horizontally from left to right with a length of 2 meters, and the arrow representing the force pointing to the left with a length representing 3 Newtons.
To calculate the work done on the object in Joules, we can use the formula:
Work = force × displacement × cos(θ)
In this case, the force is 3 Newtons, and the displacement is 2 meters. However, we don't know the angle between the force and the displacement from the given information. Without the angle, we can't calculate the work precisely.
If we assume that the force and the displacement are in the same direction (which is not the case in this scenario), then the angle (θ) would be 0 degrees. In that case, the formula becomes:
Work = force × displacement × cos(0) = force × displacement
Using this assumption, we can calculate the work done. The work would be:
Work = 3 Newtons × 2 meters = 6 Joules
So, if the force and displacement are in the same direction, the work done on the object would be 6 Joules. However, without knowing the actual angle between the force and the displacement, we cannot determine the precise work done.
