Why is gravity considered a non contact force?
Non-Contact ForcesWhile the ball is in the air, one force acting on it is gravity. Gravity pulls the ball down to the earth without touching it. This means it is an example of a non-contact force, or a force exerted on an object that does not make contact with it. Another example of a non-contact force is magnetism. Read more about magnetism.
What is accomplished when an object is moved by force?
Work is done when a force acts on an object as the object moves from one place to another. Work is defined as force times distance.
When is work not done on an object?
Work = Force x Distance. so no work is done if there is no force exerted, or if the object does not move.
How is work done by a force measured when force is in direction of displacement?
Work = (force on an object) times (displacement of the object during the time the force is applied to it).
What is required for a force to work on an object?
The force must cause the object to move.

What is required for a force to work on an object?
The force must cause the object to move.
When can work be negative physics?
If you apply force in the same direction an object moves, the work on the object is positive.If the force is in the opposite direction as the direction the object moves, the work on the object is negative.
How do we know if work is done?
In physics, work is done by a force acting on an object if the object moves in the direction of the force.
What is the scalar product of the force action on an object and the displacement caused by that force?
Work is the scalar product of the force acting on an object and the displacement caused by that force. In order for work to be done, the object must be moved in the direction of the force.
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
What is required for a force to do work on an object?
in the same direction as the object's motion.
What force causes an object to move in the direction of the force?
The force is work.
To do work how must a force make an object move?
You apply a force to an object. The object must move in the same way as the applied force
