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.
Can force change the magnitude of a body?
Yes, force can change the magnitude of a body.
When do the velocity and speed of a moving body become equal?
The velocity and speed of a moving body become equal when the motion is along a straight line with no change in direction. In such cases, the velocity and speed have the same magnitude.
When a body moves with constant velocity what is the magnitude of net force is the magnitude of force applied to keep the body moving equal to less than or more than frictional force explain?
When a body moves with constant velocity, the net force acting on it is zero as there is no acceleration. The magnitude of the force applied to keep the body moving is equal to the frictional force opposing its motion. This ensures that the forces are balanced, resulting in a constant velocity without any acceleration.
When a body has uniform velocity?
When a body has uniform velocity, it is moving in a straight line at a constant speed. This means that the magnitude and direction of its velocity remain constant over time. uniform velocity implies no acceleration present in the motion of the body.
Can a velocity of a body change its speed is constant?
No. A body with constant velocity is either stationary or going at constant speed in a constant direction. The usual interpretation of speed and velocity goes like this. A velocity is a vector with magnitude and direction. The magnitude is usually called its speed. Changing a speed must change the length of the vector and changing the length of the velocity vector has to change the velocity.

What is an angular speed of a rotating body?
Angular velocity is given as radians per second; angular speed is also the same thing. Velocity is a vector with magnitude and direction and speed a scalar with magnitude only. The magnitude is identical; velocity will define the direction of rotation ( clockwise or counterclockwise).
When a body has uniform velocity?
When a body has uniform velocity, it is moving in a straight line at a constant speed. This means that the magnitude and direction of its velocity remain constant over time. uniform velocity implies no acceleration present in the motion of the body.
How is speed of a body related its velocity?
Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.
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.
Can speed of a body change if its velocity is constant?
No. A body with constant velocity is either stationary or going at constant speed in a constant direction. The usual interpretation of speed and velocity goes like this. A velocity is a vector with magnitude and direction. The magnitude is usually called its speed. Changing a speed must change the length of the vector and changing the length of the velocity vector has to change the velocity.
If velocity dSdt and speed dSdt then what happened when a body move in a complete circle were dS0 then velocity?
Velocity is a vector, meaning it has a direction, like east, north, up. Speed isa magnitude without direction, 60 miles per hour is a speed; 60 miles per hour north is a velocity. When a care is going 60 mph in a circle the speed is constant but the velocity changes as the direction changes. The magnitude of the velocity is the same but the direction changes thus the velocity changes. Velocity changes if either the speed/magnitude or the direction change.
What is acceleration body?
Acceleration of a body is the rate at which the velocity of the body changes over time. It is a vector quantity, meaning it has both magnitude (how much the velocity changes) and direction (the direction in which the velocity is changing). The standard unit for acceleration is meters per second squared (m/s^2).
