there is no acceleration if the body is moving with constant velocity
Motion describes that something is moving. Speed describes how fast something is moving. Velocity describes how fast something is moving and in what direction its moving.
It depends on if the route is straight. If it is a straight route it would move 25 km. ---- Technically, the question states that the route is straight. Velocity is a measure of speed AND direction; any change in direction would indicate a change in velocity. The question states that the velocity, and therefore direction, is uniform (I take that to mean constant).
No force is required to keep a body moving with constant velocity.
Acceleration is defined as The rate of change of Velocity. Which means that for acceleration there must be Variable Velocity/ Speed. and not uniform
No. Speed is the magnitude of velocity. If the speed varies, so will the velocity, even if you are moving in a uniform direction.
Speed is considered a scalar while velocity is refered to as a vector. A vector can be varied with respect to its direction. Therefore, constant speed while changing direction varies the velocity
variable velocity can be defined as a moving body whose velocity changes with time
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed.
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
If there is acceleration (uniform or otherwise, but non-zero acceleration), the velocity changes. Constant velocity means that the velocity does not change.
Uniform Constant Deceleration
For velocity to be truly uniform, the object must be moving in a straight line. If that is the case then the acceleration is Zero.
Zero, since the velocity doesn't change.
If a car moving in a straight line travels equal distance in equal time no matter how small these distances may be, the car is said to be moving with a CONSTANT or Uniform Velocity.
