#1
Front (Question)

What unit do we use to measure distance?

Back (Answer)

Metres, M

#2
Front (Question)

What unit do we use to measure time?

Back (Answer)

Seconds, S

#3
Front (Question)

What unit do we use to measure speed?

Back (Answer)

Metres per second, m/s

#4
Front (Question)

What does 1 m/s mean?

Back (Answer)

One metre is travelled per second

#5
Front (Question)

What equation links speed, distance and time?

Back (Answer)

Speed = distance ÷ time or s = d ÷ t

#6
Front (Question)

Back (Answer)

#7
Front (Question)

What does mph / miles per hour mean?

Back (Answer)

We don’t use Mph in science!

#8
Front (Question)

How far will you travel in 2 hours if you are travelling at 50 mph?

Back (Answer)

100 miles ( 2 x 50 = 100)

#9
Front (Question)

I am running at 6 m/s. How far do I travel in 2 seconds?

Back (Answer)

12 m/s ( 6 x 2 = 12)

#10
Front (Question)

A lorry takes 12s to travel 48m. What is its speed?

Back (Answer)

• S = d ÷ t • S = 48 ÷ 12 • = 4 m/s

#11
Front (Question)

What is the relationship between energy, power and time?

Back (Answer)

E = p x t

#12
Front (Question)

An elephant runs for 12s and has a power of 2500 W.

Back (Answer)

• E = p x t • E = 2500 x 12 • = 30 kJ

#13
Front (Question)

What two things do we need to measure speed?

Back (Answer)

Distance and time

#14
Front (Question)

Which store of energy is DECREASING in a car as it moves down a ramp?

Back (Answer)

Gravitational potential energy

#15
Front (Question)

Which store if energy is INCREASING in a car as it moves down a ramp?

Back (Answer)

Kinetic energy

#16
Front (Question)

What is a line of inquiry?

Back (Answer)

A focused question about what you are trying to find out

#17
Front (Question)

Variable

Back (Answer)

Anything you can change

#18
Front (Question)

Independent Variable

Back (Answer)

You can change it or it might change by itself

#19
Front (Question)

Dependent Variable

Back (Answer)

Changes depending on the independent variable

#20
Front (Question)

Controlled Variable

Back (Answer)

Variable that we keep the same, they don’t affect the experiment

#21
Front (Question)

Prediction

Back (Answer)

Using scientific knowledge to suggest what you think will happen

#22
Front (Question)

Relative Motion

Back (Answer)

The speed of a moving object from the viewpoint of another moving object

#23
Front (Question)

If two object move in the SAME direction, how do you calculate their relative speed?

Back (Answer)

Subtract their individual speeds from each other

#24
Front (Question)

Of two objects are moving in OPPOSITE directions, how do you calculate their relative speed?

Back (Answer)

Add their individual speeds to one another
