Free fall

________ is a case of motion with constant acceleration.

New cards
3

instantaneous velocity

The ________ is the limit of the average velocity as the time interval approaches zero.

New cards
4

When is the x- velocity positive relative to the tangent of the slope

If the tangent to the x-t curve slopes upward to the right, then its slope is positive, the x-velocity is positive, and the motion is in the positive x-direction.

New cards
5

When is the x- velocity negative relative to the tangent of the slope

If the tangent slopes downward to the right, the slope of the x-t graph and the x-velocity are negative, and the motion is in the negative x-direction.

New cards
6

average acceleration

The change in the x-component of velocity Δv(x), divided by the time interval Δt is known as average acceleration.

New cards
7

instantaneous acceleration

The instantaneous acceleration is the limit of the average acceleration as the time interval approaches zero.
