What is the difference between speed and velocity Answer: velocity has direction
what is the equation relating average speed, time taken and distance moved?
Answer: average speed=distance moved/time taken
what is acceleration? Answer: how quick velocity is changing
what is the equation relating acceleration, change in velocity and time taken?
Answer: acceleration=change in velocity/time taken
on a distance-time graph what does the gradient symbolise? Answer: speed
on a distance-time graph what does it mean when there's a flat section? Answer: it's
stopped
on a distance-time graph what does it mean when there are curves? Answer: there's
acceleration or deceleration
on a velocity-time graph what does the gradient symbolise? Answer: acceleration
on a velocity-time graph what does it mean when there is a flat section? Answer:
steady speed
on a velocity-time graph how can you find distance travelled in a certain time?
Answer: by working out the area under the line (with limits if trying to find the
distance travelled between certain time)

, give the equation relating weight, gravitational field strength and mass Answer:
weight=mass x gravitational field strength
what does friction do? Answer: slows things down
what is the accelerating force that acts on all falling objects? Answer: gravity
what is terminal velocity? Answer: resistance force=accelerating force
what is newton's first law? Answer: balanced forces means no change in velocity
what is newton's second law? Answer: an unbalanced force means there will be
acceleration
give the equation relating force, acceleration and mass Answer: force=mass x
acceleration
what is newton's third law? (use object A and object B) Answer: that if object A
exerts a force on object B, object B with exert the same but opposite force on object
A
