In general, force and velocity do not have to be in the same direction; they can be at any angle.

What is the direction of acceleretion of a body in circular motion?
-- The acceleration is directed from the body to the center of the circle. -- The velocity is tangent to the circle at the place where the body is. That direction is also perpendicular to the acceleration at that moment.
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.
What happens when your velocity and net force are perpendicular to each other?
You travel in a circle.
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 is the direction of the force that's keeps and object moving in a circle?
The centripetal force which always acts perpendicular to the motion of the object

What is the shape of the orbit when the velocity of the satellite is everywhere perpendicular to the force of gravity?
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.
Does a magnetic field exert any pressure on a charge moving perpendicular to its direction?
Only moving charges experience force in a magnetic field. i.e.,on moving ,a charge q,with velocity v ,experiences a force in the presence of electric field(E) and magnetic field (B). It can be represented as F= q(v x B)~(Ftotal=Felectricfield + Fmagneticfield ) Force acts perpendicular to both magnetic field and velocity of the electron. Its direction is given by right hand thumb rule or screw rule. The magnetic force is zero if charge is not moving, since lvl=0.

Does force includes both speed and direction?
velocity
What should be the angle between the direction of force and the direction of motion of a body so that the work done is zero?
If the force is perpendicular (at 90 degrees) to the direction of motion, that force does no work.
In what direction should a force be applied to produce maximum torque?
In a perpendicular direction to the rotating body.
What is the speed and direction of an object called?
Speed with direction is called Velocity
Can unbalanced fores stop a moving object?
Yes. An unbalanced force can make an object go faster (if the force acts in the same directon of the movement); slow it down (opposite directions), or change its direction (if force is perpendicular to the direction of movement). All of these phenomena are called "acceleration", which for a physicist means "change of velocity".
