What do curves represent in a distance time graph? - correct answer acceleration (steepening
curve) or deceleration (leveling off curve)
How to work out the speed on a distance-time graph? - correct answer the change in y ÷ the
change in x
What is acceleration? - correct answer how quickly the velocity is changing
What can the change in velocity be? - correct answer change is speed or a change in direction

What is the unit of acceleration? - correct answer m/s²
What are gravity's two important effects? - correct answer - on the surface of a planet, it makes
all things accelerate towards the ground
- it gives everything a weight
What is mass? - correct answer amount of stuff in an object
What is the unit of mass? - correct answer kg
What is weight? - correct answer the pull of the gravitational force towards the centre of the
Earth
What is the unit of weight? - correct answer newtons
What is the formula relating mass, weight and gravity? - correct answer weight= mass x
gravitational field strength
What is the resultant force? - correct answer the overall force on a point/object
How do you calculate the resultant force? - correct answer one force + another force
If resultant force is 0 it means that... - correct answer the object won't move
If there is no resultant for on a moving object it means that... - correct answer it will move at a
constant velocity
If the resultant force on an object is not 0 it means that... - correct answer the object will
accelerate in the direction of the force
What does a non-zero resultant force produce? - correct answer acceleration
What is the formula for resultants force? - correct answer resultant force (N)= mass (kg) x
acceleration (m/s²)
What are the different forms of acceleration? - correct answer speeding up, steady speed,
starting

What is the terminal velocity? - correct answer maximum speed an object reaches and will then
remain at a steady speed
What factors does terminal velocity depend on? - correct answer shape and area
What factors affect your total stopping distance? - correct answer thinking distance and braking
distance
What is the reaction time? - correct answer the time between the driver spotting the hazard
and taking action
factors affecting thinking distance - correct answer - how fast you're going
- how dopey you are due to alcohol, fatigue, drugs or carelessness
- bad visibility due to weather, or bright oncoming lights
- distractions
What are the factors affecting your braking distance? - correct answer - how fast you're going
- how good brakes are
- how good tires are, how good grip is on road- ice/rain
What happens when a force moves an object? - correct answer energy is transferred and work
is done
What is the formula or work done? - correct answer work done= force x distance
What is gravitational potential energy? - correct answer it is energy that an object has
depending on its height, the work done against the force of gravity
What is the formula for gravitational potential energy? - correct answer gravitational potential
energy= mass x g x height
What is kinetic energy? - correct answer anything that is moving has kinetic energy
(the more it weighs, the faster its going, the bigger the kinetic energy will be)
What is the formula for kinetic energy? - correct answer 1/2 x mass x speed²
For a car to slow down kinetic energy must be... - correct answer converted into other types of
energy
For a car to stop, the kinetic energy must be... - correct answer converted into heat energy as
friction between the wheels and the brake pads, causing the temperature in the brakes to
increase
