Explaining motion P4 Questions/Answers

2
Question 1 What is the name used to describe a pair of forces?

3
Answer Interaction pair

4
Question 2 Which of these are not true about interaction pairs of forces? A) always equal in size B) opposite in direction C) act on different objects D) one of them is always friction

5
Answer Answer D – one of them is always friction.

6
Question 3 Write down the equation to calculate speed.

7
Answer Speed = Distance / Time

8
Question 4 If car has travelled 3000m in 100 minutes what is its speed in m/min and m/s?

9
Answer 30m/min and and0.5m/s

10
Question 5 Sketch a distance time graph to show a car starting from stationary, travelling at a constant speed and then stopping.

11
Answer time distance

12
Question 6 Sketch a speed time graph to show a car accelerating, then travelling at a constant speed, then slowing down to stop.

13
Answer SpeedTime

14
Question 7 Describe what is happening during the journey in this velocity time graph. 10mph velocity time

15
Answer The object is travelling at a velocity of 10mph then begins to slow down, it stops for a moment (intersection on x axis) then goes backwards.

16
Question 8 TRUE or FALSE If two objects have different masses, the heavy one moves faster than the light one?

17
Answer FALSE the heavier object moves slower than the light one.

18
