On a curved xt graph the slope of the secant represents what?

• average acceleration

• distance

• instantaneous velocity

• instant acceleration

The slope of a v-t graph gives the

• position

• acceleration

• velocity

• force

What is the shape of an xt graph that shows an object moving with a constant acceleration?

• circular

• straight and flat

• vertical

• curved

When an object is slowing down the direction of the velocity and accelleration arrows must be

• the same

• opposite

• alternating

• there will not be acceleration arrows

Which graph shows and object speeding up in the negative direction?

• Graph A

• Graph B

• Neither graph

• It is impossible to tell without a vt graph
