Explain the concept of changing speed with respect to acceleration.
Acceleration is the rate of change of velocity over time.
Acceleration is the rate of change of distance over time.
Acceleration has no effect on speed.
Acceleration is the same as speed.
On a speed-time graph, what does a steeper slope indicate?

Define terminal velocity.
The speed at which an object stops falling
The speed at which an object starts falling
The constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.

How does terminal velocity relate to acceleration?
Terminal velocity is the point at which acceleration becomes zero.
Terminal velocity increases acceleration
Terminal velocity has no effect on acceleration
Terminal velocity decreases acceleration
