If an object has no propelling force, it will be slowed down or stopped by ... - ... acts in the opposite direction to movement
friction
2 of 15
... is the resistance (friction) you get in a fluid. To reduce this, you need to make the object more streamlined
drag
3 of 15
... will be reached when frictional force = acceleration so resultant force is zero. This depends on shape and area
Terminal Velocity

Newtons ... : Resultant force is needed to make something start moving, speed up or slow down
First Law
5 of 15
... can take 5 different forms: -Starting -Stopping -Speeding Up -Slowing Down -Changing Direction
Acceleration
6 of 15
... is directly proportional to resultant force
Acceleration
7 of 15
Acceleration is inversely proportional to the ... of an object
mass
8 of 15
Newtons ... : Force = Mass x Acceleration
Second Law
9 of 15
When motion remains unchanged, it is known as ...
inertia
10 of 15
Newtons ... : When two objects interact, the forces they exert on each other are equal and opposite. If you push something, the thing will push on you just as hard
Third Law
