Acceleration Quiz

What is average acceleration defined as?

• The change in distance over time

• The change in speed over time

• The change in velocity over distance

• The change in time over speed

Which units are used to measure acceleration?

• m/s

• km/h

• m/s^2 or km/h/s

• s/m or s/km

What is the formula to calculate acceleration?

• a = (v-u) * t

• a = (v+u) / t

• a = (v-u) / t

• a = v * u * t

How can acceleration be calculated from a graph?

• By measuring the area under a speed vs time graph

• By calculating the slope of a distance vs time graph

• By finding the gradient of a speed vs time graph

• By determining the intercept of a velocity vs time graph

What is acceleration?

• The distance an object travels over a period of time.

• The rate at which an object's speed changes.

• The maximum speed an object can reach.

• The time it takes for an object to stop.

Acceleration is a vector quantity because it has:

• Only magnitude.

• Only direction.

• Both magnitude and direction.

• Neither magnitude nor direction.

How is average acceleration calculated?

• Time taken divided by change in speed.

• Change in speed divided by time taken.

• Change in speed multiplied by time taken.

• Time taken multiplied by change in speed.

How can acceleration happen ?

• Only by speeding up

• By speeding up, slowing down, or changing direction

• By changing direction only

• By increasing the engine power

What is the formula for acceleration, if v is final speed, u is initial speed and t is time taken?

• a = (v+u) / t

• a = v * u / t

• a = (v-u) * t

• a = (v-u) / t

Which type of acceleration do humans not handle well?

• Horizontal acceleration

• Vertical acceleration

• Constant acceleration

• Acceleration in a vacuum
