what does having a bigger force mean? |
it's takes longer and more energy needed for a change in momentum |
|
what's a partner force or an interaction pair |
when an object exerts a force on another object it always experiences a force in return |
|
what conditions are needed to form an interaction pair |
each force acts in a different object and the forces act in opposite directions |
|
what does falling turn gdp energy into |
kinetic energy |
|
K.E. gained = |
G.P.E lost |
|
what does work done = |
energy transfered |
|
what's kinetic energy otherwise known as |
movement |
|
how do you increase K.E. |
increase velocity apply more force |
|
G.D.P. energy stored where |
energy stored in an object |
|
three types of friction? |
grip drag slide |
|
what does friction do? |
prevent movement |
|
what's resultant force? |
the overall force decides the motion (speed or change in direction |
|
what momentum |
how much oomph how hard it would be to stop the movement |
|
what does the resultant force of zero mean |
the object will stay still |
|
if the resultant force isn't zero then? |
the momentum changes in the direction of the force |
|
what does steeper gradient mean? |
the faster the object is moving |
