to calculate distance
speed*time
2 of 12
to calculate time
distance/speed
3 of 12
to calculate velocity
displacement/time
4 of 12
to calculate acceleration
change in velocity/time
5 of 12
to calculate the change in velocity
final velocity-initial velocity
6 of 12
to calculate momentum
mass*velocity
7 of 12
elastic collision
( before)mass*velocity=(after) mass*velocity then u divide the results
8 of 12
both objects are moving to begin with
( before) (mass*velocity)+(mass*velocity)= (after)(mass*velocity)+(mass*velocity) then you divide the results
9 of 12
collisions that stick together
(before)mass*velocity= (after) mass*velocity then divide the results
10 of 12
Objects that stick together
(before) (mass*velocity) + (mass*velocity)=mass+mass*velocity= then divide the results
11 of 12
Explosions
mass*velocity=mass*velocity=then divide results
