Q

What does drag do

A

Increases as speed increases

17
Q

Newtons first law ?

A

If the resultant force on a stationary object is zero, the object will remain stationary. If the resultant force on a moving object is zero, itll just carry on moving at the same velocity

18
Q

Whats newtons third law

A

When two objects interact, the forces they exert on each other are equal and opposite

19
Q

What is momentum

A

Its maniky how much ‘oomph’ an object has

20
Q

The total momemtum before an event is thesame as what?

A

The same as after the event

21
Q

What is distance

A

How far an object has moved

22
Q

What does displacement measure

A

The distance and direction in a straight line from an objects starting to finishing point
