◉ 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
