Science 6 Friction Force Energy

Friction _____________ motion

• Works in the same direction as

• Opposes

• Has not effect on

• Pulls against

Which type of friction keeps objects from sliding around all over the place

• Static Friction

• Rolling 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

Wheels on a skateboard most likely experiences-

• Rolling Friction
• Sliding Friction
• Fluid Friction
• Static Friction

Sally experiences-

• Rolling Friction
• Sliding Friction
• Fluid Friction
• Static Friction
