With a horizontal pulling force of 10N, the horse drove the carriage with a mass of 1000kg along the horizontal road at a uniform speed of 1000m. What is the resistance to the object? What is the work done by gravity?
10N 0J
If an object with a gravity of 100N is moved at a constant speed of 2m along the horizontal direction by a horizontal pulling force of 20n, the work done by the pulling force on the object is small
What does gravity do to an object
The work done by the pulling force on the object is: W1 = FS = 20n * 2m = 40J
The work done by gravity on an object is W2 = 0
