Write a report for this
investigation.

Based on the information obtained in
this investigation, what is the relationship
between speed and the distance travelled
within the set time?

1. What are your observations after the toy car was pulled and released at
different distances of the rubber band stretched backwards?
2. Make inferences based on the observations.
3. What is the relationship between the manipulated variable and the responding
variable in this investigation?
4. Predict the distance travelled by the toy car if 6 cm and 15 cm distances are
used in your investigation.

Q

1. Which of the following shows the shortest distance travelled within the
same duration of time?
• 80 km/h • 120 km/h • 95 km/h
2. The table below shows the time taken by three types of toy cars
P, Q and R to travel 3 metres.

Car P Q R
Time taken (s) 5 6 3

Toy car _____ travels slower than toy car _____ but faster than toy

car _____.

CLICK Every vehicle that moves on the road has
a speedometer mounted on the front
panel of the driver’s seat. A speed meter Do stationary
or speedometer is important to indicate objects have speed?
the speed of a vehicle in km/h. Why?

What other factors affect the time taken by a moving object to travel? How does
speed affect the time taken for an object to travel a fixed distance? Let us do the
next activity.
