Picture one of the following:
- a hockey player about to hit a puck with their stick
- a cricket batsman about to strike the ball
- a Baseball player about to hit the ball with their bat
- a tennis player about the hit the ball with their racket
- a golfer about to hit the ball with their club
The total speed and the direction that a club or stick or racket or bat could have imparted to something at a point would be its tangential velocity. Obviously hitting something slows the striking object down.

What is uniform in uniform circular motion?
The speed of the object in motion, the radius of the curve in which it moves, the force acting on it to keep it moving in a circle, its angular velocity, and its centripetal acceleration, are all constant. Notice that its linear velocity is not constant, because the direction of its motion is always changing. Although I guess you'd have to say that its velocity is constant in polar coordinates, because the radial and tangential components are constant.
What does it mean when velocity is negative?
When velocity is negative, it means that the object is moving in the opposite direction of its positive velocity.
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.
What does it mean if velocity is negative in a physical context?
In a physical context, a negative velocity indicates that an object is moving in the opposite direction of its positive velocity.
What does the slope under the curve of a displacement versus time reveal?
There is no such thing as a "slope under the curve", so I assume that you mean "slope of the curve". If the curve is d vs. t, where d is displacement and t is time, then the slope at any given point will yield (reveal) the velocity, since velocity is defined as the rate of change of distance with respect to time. Mathematically speaking, velocity is the first derivative of position with respect to time. The second derivative - change in velocity with respect to time - is acceleration.

What is root mean square velocity?
For an object moving at a variable velocity you:calculate the square of the velocityfind its mean valuecalculate its square root.If the velocity is constant then the RMS velocity has the same value.
What does it mean if velocity is negative in a physical context?
In a physical context, a negative velocity indicates that an object is moving in the opposite direction of its positive velocity.

What does uniform circular motion mean?
Uniform circular motion is the movement of an object along a circular path at a constant speed. The object experiences a centripetal acceleration directed towards the center of the circle, which keeps it moving in a circular trajectory. The velocity of the object is tangential to the circle at any given point.
Can it be possible that a particle have constant speed must have zero acceleration?
It's possible, but not necessary, that a particle moving with constant speedhas zero acceleration. In order for acceleration to be zero, it's also necessarythat the particle be moving in a straight line.An object moving with constant speed around a curve has acceleration."Acceleration" does not mean "speeding up".
Is space is really curve?
The sir of astronomy said that space is curve but how that is possible according to me space can not curve if space is the form of curve than all galleries ,plants ,stars, and everything which belong to universe will be move in the same way but there are moving in special curve path . The curve path be may because of different forces which make them make is a curve path. The forces are well know my as . But on curve path I have a example suppose that you are moving on a path the path is curve you are moving in a straight line with any speed but it appear to as that we are moving in a curve path. in reality we are moving in straight line. same condition of earth which are moving in a curve due to same special forces not in a curve space. Now we know very wall that the curve path is due to same special forces which force any body to move in a curve path . In short the curve is due to same force , it is not mean that space is curve. If so than the shape of space is like Imagine the image
What do you mean by whirl velocity of turbine?
Whirl velocity of a turbine is determined by how fast the turbine can turn when it is moving. This is a factor considered with airplane manufacturing. Whirl velocity is the number of times in a second that a turbine can rotate, moving at a given speed.
A negative slope on the velocity vs. time graph indicates that the object is not moving.?
False. It means it is slowing Down!
What does slow mean?
Moving or proceeding with little or less than usual speed or velocity
