The force associated with Torque T is always perpendicular to the torque motion, T=FxR.
The centripetal force is always perpendicular to the motion in circular motion. It acts towards the center of the circle, keeping the object moving in a circular path.
The Centripetal Force
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.
A perpendicular force applied to an object can change its direction of motion without affecting its speed.
No, the force of gravity does not do work on a satellite when it is in motion because the direction of the force is perpendicular to the direction of motion.

No, the force of gravity does not do work on a satellite when it is in motion because the direction of the force is perpendicular to the direction of motion.
When a force is perpendicular to the direction of motion, no work is done. This is because work is defined as the product of force and displacement in the direction of the force. If the force is perpendicular, then there is no displacement in the direction of the force and thus no work is done.
If the velocity of the satellite is always perpendicular to the force of gravity, then the eccentricity of the orbit is zero, and it's perfectly circular.
True. When the force is perpendicular to the direction of motion, no work is done because work is the product of force and displacement in the direction of the force. Since there is no displacement in the direction of the force, no work is done.
Magnetic force does not do any work because it acts perpendicular to the direction of motion of the charged particle. Work is defined as force acting in the direction of motion, and since magnetic force acts perpendicular to the motion, it does not transfer energy to the particle in the form of work.
The normal force is a force that is always perpendicular to the two sliding surfaces. It is the force exerted by a surface to support the weight of an object resting on it.
Motion Perpendicular to the ground is called horizontal motion.
The force that keeps an object moving in a circle is directed towards the center of the circle. This force is called the centripetal force and it is responsible for changing the object's direction continuously, keeping it in circular motion.
