If speed increases, or if the moving object curves up or down or to the right or
to the left, or if speed decreases, any of these events is called "acceleration".
Accelerated body
Positive Acceleration refers to the force acting on an object whose speed increases as it moves away from its original starting position. If the velocity is increasing along with time it is called positive acceleration, and if the velocity decreases it is negative acceleration.
It doesn't. But velocity does effect mass : as velocity increases, mass increases.
When a stream's discharge increases, erosive energy increases.
Kinetic Energy increases as velocity increases. Kinetic Energy = 1/2 * Mass * Velocity2
As height increases, the velocity generally decreases due to the effect of gravity. This is because potential energy increases while kinetic energy decreases, resulting in a slower velocity.
Velocity increases..
when speed increases, velocity changes.
When something increases in velocity, its momentum would increase because momentum is equal to its mass * velocity. This means that the momentum and velocity are proportional, so twice the velocity is twice the momentum, and so on.
When an object undergoes acceleration, it is the velocity that increases. Acceleration is the rate of change of velocity, so an object experiencing acceleration will have its velocity change over time, either by speeding up, slowing down, or changing direction.
When velocity increases, kinetic energy also increases. Kinetic energy of an object is directly proportional to its velocity squared, so even a small increase in velocity can result in a significant increase in kinetic energy.
Increase of velocity over a period of time is called acceleration.
