What is the exertion of a force on an object called that produces motion in the direction of a force?
Work occurs when a force causes an object to move in the direction of the force.
What is the direction of the force of gravity?
The force of gravity acts towards the center of mass of the object in question.
What is the effect of gravity on velocity?
Gravity is a force and any force acting on a body changes its velocity in the direction of the force.
When is work said to be done against the force of gravity?
All bodies with mass are attracted to the Earth by gravity, so when a body is raised you must do work to raise it. This work is equal to force x height, if force is in Newtons and height in meters, the work is in units of Joules.
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.

What direction does the force of gravity apply to the rollercoaster car?
From what I know, Force of Gravity always acts in the vertically downward direction.

What is the downward force of gravity?
The most usual downward force is the force of gravity; the weight of an object exerts force in a downward direction. There are also other forces which can be exerted in that direction. If you wanted to, you could fire a gun in a downward direction, in which case the explosive force of the gun is added to the force of gravity.
The work done by gravity during the descent of a projectile motion is?
The answer is positive because the force and direction are the same, therefore work is also positive.
The force of gravity is responsible for changing the what in which a satellite moves?
The force of gravity will change the satellites direction, and therefore its velocity.
What is work done by a coolie walking on a horizontal platform with a load on his head?
The displacement of the load is perpendicular to the direction of force therefore work done by the coolie against the force of gravity is zero.
Is the force of gravity is a vector?
Yes. It results in a force that has a magnitude and a direction, and this is the definition of a force vector.
How many direction does force of gravity has?
Exactly one direction . . . between the centers of the two masses that are being drawn together by gravity.
