Forces - Drag/ Friction and balanced/ unbalanced Flashcards
1
Q
Friction
A
- force that resist movement
- due to contact between surfaces
2
Q
Lubrication
A
-a substance that reduces friction
3
Q
Water resistance
A
- force on an object moving through the water
- causes it to slow down
4
Q
Drag force
A
- force acting on an object moving through air/water
- slows it down
5
Q
Streamlined
A
-shaped to reduce resistance to motion from air/water
6
Q
Balanced
A
-forced acting on an object that are the same size but act in different or opposite directions
7
Q
Unbalanced
A
-opposing forces on an object that are unequal
8
Q
Equilibrium state
A
Balanced object
- equal forces
- stationary object
9
Q
Driving force
A
-the force that is pushing or pulling something
10
Q
Resistive force
A
-any force that slows down a moving object
11
Q
Isaac Newton discovery
A
-the earths gravity kept the moon in orbit
