Forces & Speed Flashcards
The force on an object moving through the air that causes it to slow down (also known as drag).
Air resistance
Forces acting on an object that are the same size but act in opposite directions.
Balanced
To squash into a smaller space.
Compress
To change shape.
Deform
The force that resists movement because of contact between surfaces.
Friction
A non-contact force that acts between two masses.
Gravity
A substance that reduces friction between surfaces when they rub together.
Lubrication
The force between two magnets, or a magnet and a magnetic material.
Magnetic force
The amount of matter (stuff) a thing is made up of.
Mass
Two examples of forces.
Push & Pull
Shaped to reduce resistance to motion from air or water.
Streamlined
A stretching force.
Tension
Opposing forces on an object that are unequal.
Unbalanced
The force on an object moving through water that causes it to slow down (also known as drag).
Water resistance
The force of the Earth on an object due to its mass.
