This is a test I made to help with an end of unit test I'm going to take soon (it's not the real GCSE). It's probably best to take this after you've revised, to test how much you know, or you could use it to jog your memory. Please like! (Or whatever you can do - positively - on this website). Good luck on any Physics test you have - P3 is all about equations, so practise practise practise!!!

OCR Gateway GCSE P3 Revision Quiz

Question 1 of 30

1

How can you measure the speed of an object?

Select one or more of the following:

  • metres per second (m/s)

  • kilometres per hour (kph)

  • miles per hour (mph)

  • yards per minute (ypm)

Explanation

Question 2 of 30

1

The faster the speed of an object:

Select one or more of the following:

  • the greater the distance it travels

  • the lighter the object is

  • the shorter the time it takes to travel a particular distance

  • the quicker the acceleration of the object

  • the larger the surface area of the object, therefore creating more drag

Explanation

Question 3 of 30

1

speed = .... ?

Select one of the following:

  • distance * time

  • speed / distance

Explanation

Question 4 of 30

1

Why is average distance used?

Select one of the following:

  • to make the answer more reliable

  • the speed may change over a given distance, so the average distance over the whole journey is used

  • the speed may change direction, so it is better to use an average DISTANCE instead of speed

Explanation

Question 5 of 30

1

Explanation

Question 8 of 30

1

(distance - time graphs) a straight diagonal line shows...

Select one of the following:

  • The object is going backwards

  • The object is travelling in a straight line

Explanation

Question 10 of 30

1

(distance-time graphs) a steeper diagonal line means....

Select one of the following:

  • an increase in speed (object is going faster than it was before)

  • object is accelerating

  • car has gone past the speed limit

Explanation

Question 11 of 30

1

(distance-time graphs) a diagonal line going downwards means....

Select one of the following:

  • Object is moving slower

  • object is going backwards

Explanation

Question 12 of 30

1

How do you work out the speed of an object on a distance-time graph?

Select one of the following:

  • divide the area of the time and divide it by the length of the distance

  • take any 2 points on the graph and read off the distance travelled for that part of the journey and the time taken to get there

Explanation

Question 13 of 30

1

the acceleration / deceleration of an object is..... ?

Select one or more of the following:

  • the change in speed per second

  • how fast the object is moving

Explanation

Question 14 of 30

1

how do you measure acceleration and deceleration?

Select one or more of the following:

  • acceleration = measured in:
    m/s * m/s (a.k.a. metres per second squared)

  • deceleration = measured in:
    -m/s * -m/s (a.k.a. - metres per second squared)

  • m/s, kph or mph

Explanation

Question 15 of 30

1

How do you work out the acceleration of a moving object?

Select one or more of the following:
