OCR Gateway GCSE P3 Revision Quiz

Description

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!!!

Resource summary

Question 1

Question
How can you measure the speed of an object?
Answer
  • metres per second (m/s)
  • kilometres per hour (kph)
  • miles per hour (mph)
  • yards per minute (ypm)

Question 2

Question
The faster the speed of an object:
Answer
  • 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

Question 3

Question
speed = .... ?
Answer
  • distance * time
  • ((u+v)/2) * t
  • distance / time
  • speed / distance

Question 4

Question
Why is average distance used?
Answer
  • 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

Question 5

Question
How do speed cameras work?
Answer
  • They generally take 3 pictures of several vehicles a certain time apart
  • they generally take 2 pictures of 1 vehicle a certain time apart

Question 6

Question
What is the formula for calculating the speed of a car using speed cameras?
Answer
  • speed of car = distance travelled between pictures/ time taken between 1st and 2nd picture
  • speed of vehicle = distance travelled/ time taken between 2nd and 1st picture

Question 7

Question
(Distance-time graphs) The steeper the gradient....
Answer
  • the greater the distance travelled within a short amount of time
  • the greater the speed
  • the quicker the accelertion

Question 8

Question
(distance - time graphs) a straight diagonal line shows...
Answer
  • a steady speed
  • acceleration

Question 9

Question
(distance-time graphs) a straight horizontal line (---------) shows.....
Answer
  • No movement (stationary)
  • The object is going backwards
  • The object is travelling in a straight line

Question 10

Question
(distance-time graphs) a steeper diagonal line means....
Answer
  • an increase in speed (object is going faster than it was before)
  • object is moving at a steady speed
  • object is accelerating
  • car has gone past the speed limit

Question 11

Question
(distance-time graphs) a diagonal line going downwards means....
Answer
  • The object is decellerating
  • Object is moving slower
  • object is going backwards

Question 12

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

Question 13

Question
the acceleration / deceleration of an object is..... ?
Answer
  • the change in speed per second
  • how fast the object is moving

Question 14

Question
how do you measure acceleration and deceleration?
Answer
  • 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

Question 15

Question
How do you work out the acceleration of a moving object?
Answer
  • change in speed/ time taken for change in speed
  • acceleration = (final velocity - initial velocity) / time
  • s = ((u + v) /2) * t

Question 16

Question
Example question: a car accelerates at 1.5 m/s2 for 12 seconds. Calculate the change in speed of the car
Answer
  • 18 m/s
  • 8 m/s
  • 8 m/s2

Question 17

Question
(speed-time graphs) a horizontal line means...
Answer
  • No acceleration (0 m/s2)
  • Constant acceleration

Question 18

Question
(speed-time graphs) a positive diagonal line shows....
Answer
  • acceleration
  • an increase in speed

Question 19

Question
(speed-time graphs) a negative diagonal line shows..
Answer
  • deceleration
  • going backwards

Question 20

Question
(speed-time graphs) the area underneath the speed-time can be used to measure....
Answer
  • distance travelled
  • total time taken

Question 21

Question
How would you calculate the total distance travelled on a speed-time graph?
Answer
  • Cut the graph into triangles and rectangles, then find the area for each shape and add them all up
  • multiply the y-axis by the x-axis

Question 22

Question
What is Force measured in?
Answer
  • Newtons
  • Gravity
  • kg

Question 23

Question
Forces can cause objects to....?
Answer
  • accelerate
  • decellerate
  • to be heavier

Question 24

Question
Weight causes an object to have.... ?
Answer
  • gravity
  • force
  • more acceleration

Question 25

Question
How does friction affect a car?
Answer
  • causes it to slow down
  • causes sparks in the wheels
  • makes it go faster

Question 26

Question
What happens when a sky diver opens up a parachute mid-jump?
Answer
  • Air resistance
  • Friction
  • Gravity

Question 27

Question
What happens to a sky-diver mid-jump when air resistance and weight are balanced?
Answer
  • they stay at a constant speed
  • they don't move and stay stock-still in mid-air
  • they accelerate

Question 28

Question
if an unbalanced force acts, the acceleration of an object will depend on: ?
Answer
  • the force applied to the object
  • the mass of the object
  • the speed of the object
  • the surface area of the object (larger surface area will create more drag)
  • the density of the object

Question 29

Question
more mass = ... ?
Answer
  • = more acceleration
  • = less acceleration
  • = less kinetic energy

Question 30

Question
What is the formula for the relationship between force, mass and acceleation resultant force (N) = .... ?
Answer
  • = mass (kg) * acceleration (m/s2)
  • = work done * time (s)
  • = acceleration (m/s2) / mass (kg)
