Q
What is the formula for work done on an object by a constant force?
A
Work done (W) = F * x * cos(θ)
Where F is the magnitude of the force, x is the magnitude of the displacement, and θ is the angle between the force and the displacement.
3
Q
What does the Work-Energy Theorem state?
A
The work done on an object by a net force is equal to the change in the object’s kinetic energy.
4
Q
What is a Conservative force?
A
A force for which the work done in moving an object between two points is independent of the path taken.
5
Q
What is a Non-Conservative force?
A
A force for which the work done in moving an object between two points is dependent on the path taken.
6
Q
What is Power in terms of work?
A
Power is the rate at which work is done or energy is expended.
