Falling
100
Has no direction
What is distance?
100
A graph showing the total distance travelled by an object as time progresses
What is a distance - time graph?
100
The rate at which speed changes
What is acceleration?
100
Every action has an equal but opposite reaction
What is Newton's Third Law?
100
The force that pulls objects down to the surface of a planet
What is weight?
200
Has direction
What is displacement?
200
An object at rest (stationary)
What does a horizontal distance-time graph show?
200
Negative acceleration
What is deceleration?
200
Anything at rest will stay that way unless pushed or pulled
What is Newton's First Law?
200
The rate of acceleration at which objects fall
What is gravity?
300
Speed at any moment during travel
What is instantaneous speed?
300
Speed
What does the gradient show?
300
change in speed (v-u) _______________________ time taken for the change (t)
What is acceleration calculated by?
300
If a force is applied to an object the object will accelerate and the acceleration will depend on the mass of the object
What is Newton's Second Law?
300
When there is no acceleration and the object falls at a constant speed
What is terminal velocity?
400
The time time taken to travel a specific distance
What is average speed?
400
The distance that an object has travelled up to that point
What is the area under a speed-time graph?
400
Friction, air resistance/drag, buoyancy, surface tension, lift, thrust
What is contact forces?
400
A force that is exerted on an object by the expulsion or acceleration of mass in one direction
What is thrust?
400
When an object pushes air out of its way as it falls
What is air resistance?
500
Speed in a given direction
What is velocity?
500
The horizontal axis
What axis is time placed on?
500
Weight, electrostatic force, magnetic force
What is non-contact forces?
500
Force = Mass x Acceleration
What is Newton's Second Law as an equation?
500
A measure of how much useful energy is retained in a conversion
What is efficiency?
