Which quantity describes how quickly a jeepney's velocity changes?

A tricycle rounds a curve at steady speed. Why does it still have acceleration?

The dots mark a cart's positions at equal time intervals. What happens to its speed as it moves?

A moving cart experiences zero net force. What happens to its motion while this condition continues?

The cart has a mass of 3 kg. What acceleration do the horizontal forces shown produce?

A jeepney travels east while braking produces a westward net force. In which direction is its acceleration?

Use the graph for a cart whose mass stays unchanged. How does doubling the net force affect its acceleration?

Which relationship does the graph show while net force is held constant?

Which equation summarizes Newton's law of acceleration?

What net force is needed to give an 8 kg cart an acceleration of $2{\text{m/s}}^2$?

A net force of 35 N produces an acceleration of $5{\text{m/s}}^2$. What is the object's mass?

Cart A has twice the mass of Cart B and receives twice its net force. How do their accelerations compare?

With engine force and resistance unchanged, what should a designer do to help a race car gain speed more quickly?

Two identical hanging masses are joined by a string over an ideal pulley. Released from rest, what do they do?

The hanging masses shown are released from rest using an ideal pulley and string. What happens to the mass on the left?

During motion in an ideal Atwood machine, what does a taut string that does not stretch require of the two masses?

A group varies the net force on a cart. Which quantity must stay unchanged to isolate its effect on acceleration?

A group adds mass to a hanging load that pulls a cart. Why is this not a clean test of changing force alone?

A feather and a bowling ball are dropped together from the same height in a vacuum. Why do they reach the floor together?

In air, a feather usually reaches the ground after a bowling ball dropped beside it. What best explains the difference?
