Has not effect on
Pulls against
Which type of friction keeps objects from sliding around all over the place
Static Friction

Fluid Friction
Sliding Friction
Imagine you decide to jump out of an airplane 🛩
Which force is going to pull you down towards earth
Fluid Friction
Static Friction
Gravity
The wind from the airplane
When you jump out of a plane to go skydiving 🪂 you thankfully have a parachute so you can safely land 🛫. Which answer choice explains why the parachute helps you land safely
While gravity pulls you down very quickly, Air Resistance (fluid friction) pushes back against gravity and your parachute, slowing you down
While gravity pushes you down very slowly, Air Resistance (fluid friction) pulls back against gravity and your parachute, which means you can land safely
When you have a parachute gravity is not able to pull you down as fast as it normally can
The parachute will get caught on something on your way down which will save your life
