what is speed?
speed is the distance travelled in a certain time.
1 of 9
give the equation for finding speed(m/s)
speed(m/s)= distance travelled(m) / time taken(s)
2 of 9
on a distance-time graph what does a steeping curve represent?
speeding up or acceleration
3 of 9
what is displacement?
when distance is given with a particular indication of direction
4 of 9
when would a force occur?
when two objects interract
5 of 9
give the equation for momentum
momentum=mass x velocity
6 of 9
what does the change in momentum depend on?(give equation)
change of momentum(kg m/s)=resultant force(n) x time it acts for(s)
7 of 9
what is work done?
energy transferred
8 of 9
what is gravitational potential energy?
the energy stored in an object when you raise the height (against gravity)
