What must change when a body is accelerating?
A moving body can be accelerated by applying a force. This force will act to increase velocity, decrease velocity or change the direction the body is moving. All three of these are acceleration.
How is the speed of a body related to its velocity?
The speed is the MAGNITUDE of the velocity, i.e., without regard to the direction.
Is it possible when a body to have acceleration when moving constant speed?
Yes. "Acceleration" does not mean "speeding up". It means any change in speedor direction of motion. If the body is moving on a curve, even at a constant speed,its direction is changing, so there is acceleration.
When do speed and velocity become equal?
speed and velocity becomes equal when a body is moving on a straight road without changing its direction.
How can a body be accelerating when moving at constant speed?
A body is being accelerated if its speed OR direction are changing.A satellite in a perfectly circular orbit around the earth ... like a TV satellite ... is moving at constant speed. But, technically, since its direction is always changing, to keep it on a circle, it's experiencing constant acceleration.
If net force is zero then the body will move or not?
If the net force on a body is zero, then the body will not accelerate ... its speed and direction of motion won't change. If it was moving a second ago, then it will continue moving at the same speed and in the same direction. If it was not moving a second ago, it won't start moving.

When do forces balance?
Balanced forces occur when a body is at rest, and when a body is moving at a constant speed in a constant direction.
What happens to the velocity of a moving body if you change the speed at which the body is moving?
The velocity changes. called acceleration.
Can a speed of a body be negative?
The 'speed' of a body cannot be negative. But if you are stating the 'velocity' then it can be negative. Negative velocity means it is going opposite to the direction that you decided to call the positive direction.
Can a body moving with uniform speed have variable velocity?
Yes it can.When a body moves in a circular path keeping its speed uniform then it will have variable vilocity as vilocity is the speed in a particular direction and while moving in a circular path its direction keeps changing and so does vilocity

Why the velocity and acceleration of body moving with uniform speed in circular path will be mutually perpendicular?
as direction is changing
What happens to the velocity of a moving body if you change the direction in which the body is moving?
It depends how you changed the direction of the body. If the body is hit by an external force in the direction of motion, the velocity should increase. If the body is hit by an external force in the opposite direction of motion, velocity will decrease.
