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 would the net force be on an object moving at constant velocity?
In order for an object to travel with constant velocity the sum of forces acting on it must be zero
What do you need in order to have a Force greater than zero acting on an object?
Push it, or pull it. You may have to push hard enough to overcome a force of friction.
Describe what the forces acting on an object must be in order for the net force to be zero?
The vector sum of the forces must be zero.
What is an object that acts as if there no forces acting on it all?
Inert- in order for any object to do anything, there has to be a force of some kind acting upon it, whether it be kinetic, heat, light, electrical, chemical or any other type of energy. An object that has nothing acting upon it doesn't do anything, because it can't.
What is required to get a stationary object moving?
An outside force is needed. If friction comes into play (which it likely will), the magnitude of the applied force must be greater than the force of friction acting upon the object in order for the object to move. FYI, the force of friction is equal to the coefficient of static friction times the normal force (equal to the weight of the object).
If an object is not moving can there still be a force acting on it?
According to Law of Inertia, an object will remain in its state of motion, either at rest or moving until an external unbalanced force acts on it. So if the object is at rest, some external force (F) has to be applied in order to move that object. Law of Inertia is actually a second law, out of three Newton's laws of motion.
How much force is needed to move an object?
No force is needed to keep an object moving. An object with no forces on it keeps moving at a constant speed in a straight line. If there is any force acting on it to make it slow down, then you need just enough force to cancel the first one, in order to keep it moving.
How does Archimedes' principle relate the buoyant force acting on an object to the fluid displaced by the object?
Well, as an object is in a fluid, it displaces the water and more of one or more different objects same or different will cause more water displacement.
Is air resistance a contact or non contact force?
Air resistance is a contact force because you are in contact with the air in order to apply that force.
Which set of conditions must be satisfied in order for an object to move in a circular path at a constant speed?
Well you shall need the initial force which propels the object, and there should be no hindering forces acting on the object when it is in motion. However all these forces will mean nothing without a force 'holding' the object onto the centre of rotation i.e. force of gravity, tensional force e.t.c.
In an order for a stationary object to begin to movewhat must happen happen to the force that are acting up on it?
