Rate of change of speed formula - Average Rate Of Change In Calculus (w/ Step

Variable speed: An article is said to be in variable speed while the object covers a different distance at the same intervals of times.

The four examples below show the slope for different linear functions.

So, we can say that the human perception of speed is relative.

The perpendicular force component will cause the object to move along a circular pathway as it creates a centripetal acceleration, and the parallel force component will cause the object to accelerate along the tangent as it creates tangential acceleration.

The marginal cost is the derivative of the cost function.

Therefore, on giving a push to a body, the body changes its position.
