PHY101 Key Physics Concepts: Motion, Forces,
Energy, Electricity, Gravitation, Orbits, and Safety
Principles
velocity has direction - What is the difference between speed and velocity
average speed=distance moved/time taken - what is the equation relating average speed, time
taken and distance moved?
how quick velocity is changing - what is acceleration?
acceleration=change in velocity/time taken - what is the equation relating acceleration,
change in velocity and time taken?
speed - on a distance-time graph what does the gradient symbolise?
it's stopped - on a distance-time graph what does it mean when there's a flat
section?
there's acceleration or deceleration - on a distance-time graph what does it mean when there
are curves?
acceleration - on a velocity-time graph what does the gradient symbolise?
steady speed - on a velocity-time graph what does it mean when there is a flat
section?
, by working out the area under the line (with limits if trying to find the distance travelled
between certain time) - on a velocity-time graph how can you find distance travelled in a
certain time?
gravity - what is weight caused by?
the force of attraction between all masses - what is gravity?
false - mass includes the force of gravity. true or false?
weight=mass x gravitational field strength - give the equation relating weight, gravitational
field strength and mass
slows things down - what does friction do?
gravity - what is the accelerating force that acts on all falling objects?
resistance force=accelerating force - what is terminal velocity?
balanced forces means no change in velocity - what is newton's first law?
an unbalanced force means there will be acceleration - what is newton's second
law?
force=mass x acceleration - give the equation relating force, acceleration and mass
that if object A exerts a force on object B, object B with exert the same but opposite force on
object A - what is newton's third law? (use object A and object B)
a quantity which has size - what is a scalar quantity?
a quantity which has size and direction - what is a vector quantity?
