Forces vocabulary

Unbalanced forces

• Forces that act on an object and cancel each other out.

• Forces that act on an object and don't cancel out each other; unbalanced forces cause a change in motion.

• Forces that are equal in size and opposite in direction.

• Forces that only act on stationary objects.

Buoyant force

• The upward force exerted on an object by water

• The downward force exerted by gravity on an object

• The force that opposes motion through a fluid

• The force exerted by a solid object on a fluid

Gravitational force

• The pull of all objects in the universe on one another

• A force that repels objects away from each other

• The force that keeps planets in orbit around the sun

• A type of frictional force between two surfaces

Gravity

• The force of repulsion between objects

• The force of attraction between objects

• The force that causes objects to float

• The force that opposes motion

Magnetic force

• The force produced by a magnet

• A type of gravitational force

• A force that repels all objects

• A force that only affects metals

Net force

• The total weight of an object

• The combination of all the forces acting on an object

• The force exerted by gravity on an object

• The force that opposes motion

Magnetic

• Having the property of attracting iron objects

• A type of metal that is non-reactive

• A term used to describe electrical conductivity

• A characteristic of materials that repel magnets

Friction

• A force that opposes motion

• A force that enhances motion

• A type of energy

• A measure of speed

Force

• A type of energy that can be stored

• A push or a pull that may cause an object to move, stop or change direction

• A measure of the mass of an object

• A unit of measurement for distance

Balanced forces

• Forces that act on an object but cancel out each other

• Forces that cause an object to accelerate

• Forces that are unequal and cause motion

• Forces that act in the same direction and increase speed
