CORRECT VERIFIED ANSWERS ALREADY A+ GRADED
Position + type of quantity
ANSWER-Distance from fixed origin
It's a vector
Displacement + type of quantity
ANSWER-Similar to position, but can be measured from any point.
It's a vector
Velocity
ANSWER-Rate of change of position
,Difference between displacement and distance
ANSWER-Distance is scalar quantity so doesn't involve direction
Difference between velocity and speed
ANSWER-Speed is scalar quantity so doesn't involve direction whereas
velocity is a vector so includes direction
Instantaneous velocity + how to find from graph?
ANSWER-Velocity at instant of time it is measured. Find by drawing
tangent at point and finding gradient
Difference between acceleration and magnitude of acceleration
ANSWER-Acceleration is the vector quantity. Can be negative.
Magnitude of acceleration is the size of the acceleration, it's a scalar so
doesn't care about direction.
How to draw diagram of object's motion e.g x=t²
,ANSWER-Draw a line to represent x and mark on points at specific
times, labelling t=1,2,3, etc
Area under acceleration time graph
ANSWER-Change in velocity between two intervals
Calculus equations relating displacement, velocity, acceleration
ANSWER-v=ds/dt so s=∫vdt
a=dv/dt=d²s/dt² so v=∫adt
ABC are markers on straight line. Object travelling with constant
acceleration, a, in straight line takes time t₁ from A to B distance s₁ and
time t₂ to go from B to C distance s₂. Steps to find acceleration and
initial velocity
ANSWER-Set up simultaneous equations. One suvat for AB with t=₁ and
s=s₁.
One suvat for AC (whole journey) with t=t₁+t₂ and s=s₁+s₂
a and u are same for both
, How to work out position function from v-t graph
ANSWER-Split graph into shapes such as trapezia and triangles at
appropriate time intervals, working out their areas and addings. Some
areas will be in terms of t, some will be constants
How to find largest/smallest distance between two objects given their
position functions?
ANSWER-Subtract one position function from the other to get the
function of the distance between them
Find max/min point with respect to t
Average speed
ANSWER-Total distance travelled over elapsed time
Average velocity
ANSWER-Overall displacement over elapsed time
