Speed Measurement Quiz

What is the formula for calculating speed?

• speed = distance × time

• speed = distance / time

• speed = time / distance

• speed = distance + time

How is speed usually expressed?

• meters per hour

• kilometers per second

• meters per second

• kilometers per hour

What is the average speed of an object?

• The speed at the start of the journey

• The speed at the end of the journey

• The total distance divided by total time

• The speed at one particular point

What is the formula for calculating instantaneous speed?

• instantaneous speed = length of card × time taken to break beam

• instantaneous speed = length of card / time taken to break beam

• instantaneous speed = time taken to break beam / length of card

• instantaneous speed = length of card + time taken to break beam

What is an example of measuring average speed?

• Looking at the speedometer in the car

• Travelling 70km in 2 hours by car

• Measuring the length of a card

• Timing a card passing through a light gate

What is the purpose of speed-time graphs?

• To plot the speed of an object at every point in its journey

• To measure the distance between two points

• To calculate the weight of an object

• To determine the color of an object

What is the formula for the area of a rectangle?

• Base x height

• 1/2 x base x height

• Length x width

• Base x width

What is the formula for the area of a triangle?

• 1/2 x base x height

• Base x height

• Length x width

• Base x width

What is Newton’s First Law of Motion?

• An object in motion stays in motion unless acted upon by an unbalanced force

• Force equals mass times acceleration

• For every action, there is an equal and opposite reaction

• Energy cannot be created or destroyed

What is friction?

• A force that speeds up an object

• A force that opposes the motion of an object

• A force that changes the color of an object

• A force that increases the mass of an object
