AQA GCSE PHYSICS QUESTIONS AND
ANSWERS
What is speed? - answer how fast something is going
How do you work out the speed? - answer speed= distance ÷ time
What is velocity - answer speed with direction
What do distance-time graphs show? - answer how something is travelling over a period of time
What is the gradient of a distance-time graph equal to? - answer speed- how fast the object is
travelling
What does the downwards gradient on a distance-time graph show? - answer it means its going
back towards its starting location
What do the flat sections on a distance-time graph mean? - answer it's stationary
What do straight up hill or down hill sections mean? - answer it's travelling at a steady speed
The steeper the distance-time graph... - answer the faster it's going
What do curves represent in a distance time graph? - answer acceleration (steepening curve) or
deceleration (leveling off curve)
How to work out the speed on a distance-time graph? - answer the change in y ÷ the change in
x
,What is acceleration? - answer how quickly the velocity is changing
What can the change in velocity be? - answer change is speed or a change in direction
What is the formula for acceleration? - answer acceleration= change in velocity ÷ time taken
What does the gradient equal on velocity-time graph? - answer acceleration
What does the flat sections on a velocity-time graph represent? - answer steady sped
The steeper the velocity-time graph... - answer the greater the acceleration or deceleration
What do the uphill sections mean on a velocity-time graph (/)? - answer acceleration
What do the downhill sections mean on a velocity-time graph (\)? - answer deceleration
What does the area under any section of the velocity-time graph (or all of it) mean? - answer
distance travelled in that time interval
What does a curve mean on a velocity-time graph? - answer changing acceleration
What is the unit of acceleration? - answer m/s²
What are gravity's two important effects? - answer - on the surface of a planet, it makes all
things accelerate towards the ground
- it gives everything a weight
, What is mass? - answer amount of stuff in an object
What is the unit of mass? - answer kg
What is weight? - answer the pull of the gravitational force towards the centre of the Earth
What is the unit of weight? - answer newtons
What is the formula relating mass, weight and gravity? - answer weight= mass x gravitational
field strength
What is the resultant force? - answer the overall force on a point/object
How do you calculate the resultant force? - answer one force + another force
If resultant force is 0 it means that... - answer the object won't move
If there is no resultant for on a moving object it means that... - answer it will move at a constant
velocity
If the resultant force on an object is not 0 it means that... - answer the object will accelerate in
the direction of the force
What does a non-zero resultant force produce? - answer acceleration
What is the formula for resultants force? - answer resultant force (N)= mass (kg) x acceleration
(m/s²)
