Why is a ball an example of simple harmonic motion?
because its motion is done repeatedly
When the force acting on an objects points at least partially in the blank direction of the motion the work done is considered to be what?
Positive work is work done in the direction of motion, while negative work is work done in the opposite direction from the motion.opposite
When force and motion are going in the same direction is work being done?
When force is opposite to the direction of motion, no work is done. The object to which the force is applied must move in the direction of the force in order for work to be done.
What is difference between work motion and force?
motion is the movement of an object and force is the power or work done to move the object
Give five example each of the situation when the work is done or when the work is not done?
give me a 5 situation that work is done
Can work be done on a system if there is no motion?
no
What should be the angle between the direction o foce and the direction of motion of a body so that the work done is zero?
Work is zero when the force is perpendicular to the direction of motion, as it is, for example, in a circular gravitational orbit.

When force is opposite to the direction of motion, no work is done. The object to which the force is applied must move in the direction of the force in order for work to be done.
When a force changes the motion of an object what is done?
work
When force is to the direction of motion no work is done?
No. Only if you are applying the same amount of force then there is no motion. If you are applying more force (the object is moving) then there is work being done.

motion is the movement of an object and force is the power or work done to move the object
Give five example each of the situation when the work is done or when the work is not done?
give me a 5 situation that work is done
When force is perpendicular to the direction of motion is work done?
No. At least not by the force that's perpendicular to the motion. When you push a baby stroller (or a car), you do work, but the force of gravity, downward and perpendicular to the motion, doesn't.
How do you define the scientific form of work?
the exertion of force in a same direction; work can not be done without motion
How much work is done by the surface molecules pushing upward on the object when it moved horizontally?
If there is no vertical motion, then no work is done by any vertical forces.
