Science summative trimester 2 practice

What is a reference point?

• A stationary object used to describe motion

• A moving object used to measure speed

• The final position of an object

• The time taken for an object to move

Why is a reference point important?

• To measure displacement

• To describe motion

• To calculate time

• To calculate speed

Which of the following is NOT a reference point?

• A tree

• A moving car

• A building

• A lighthouse

What is the difference between distance and displacement?

• Distance includes direction, displacement does not

• Displacement is the total path traveled

• Distance is a scalar quantity; displacement is a vector

Which of the following is a scalar quantity?

• Displacement

• Velocity

• Distance

• Acceleration

If a car travels 5 km east and 3 km west, what is the displacement?

• 8 km

• 2 km east

• 2 km west

• 3 km

A runner completes a 400 m circular track. What is the displacement?

• 400 m

• 200 m

• 0 m

• 800 m

A person walks 10 m north, then 6 m south. What is the total distance traveled?

• 4 m

• 16 m

• 10 m

A person walks 10 m north, then 6 m south. What is the displacement?

• 4 m north

• 16 m

• 10 m

• 6 m south

Which formula represents speed?

• Speed = Distance × Time

• Speed = Distance ÷ Time

• Speed = Time + Distance

• Speed = Distance + Time
