Forces Revision Flashcards
The Force on an object moving through the air that causes it to slow it down
Air resistance / Drag
The force of the Earth on an object due to its mass
Weight
The force on an object moving through water that causes it to slow down
Water resistance / Drag
Opposing forces on an object that are equal
Unbalanced
A stretching force
Tension
Shaped to reduce resistance to motion from air or water
Streamlined
The force that pushes you up from the floor
Reaction
A force moving an object away from an object
Push
An object moving an object towards it
Pull
A piece of equipment used to measure weight in nwewtons
Newton meter
The unit of force
Newton (N)
The amount of matter / stuff a thing is made up of
Mass
The force between two magnets, or a magnet and a magnetic material
Magnetic force
A substance that reduces friction between surfaces when they rub together
Lubrication
A unit of mass
Kilograms (kg)
A non-contact force that acts between two masses
Gravity
The force that resists movement because of contact between two surfaces
Friction
A region where something feels a force
Field
The amount by which a spring will not return to its original length when the force is removed
Elastic limit
When two objects interact there is a force on each one that is the same size but in opposing direction
Interaction pair
The force acting between two charged objects
Electrostatic force
The amount by which an object gets longer when a force is applied
Extension
To change shape
Deform
The force that is pulling or pushing something
Driving force
