Unbalanced Forces

Forces acting on an object cause a change in its direction because they don't cancel out.

Balanced Forces

Forces acting on an object that cancel each other out.

Pressure Formula

Force / area

One pascal

1 N/m squared

Liquid Pressure Formula

Depth x gravity x height

Centrepital Force

Tension, weight due to gravity, and friction

Gravity Formula

weight / mass

Weight formula

mass x gravity

Friction

A force that slows objects down when it rubs with something else.

Upthrust

A force from water that pushes things up

Air resistance

A force that slows things down when moving through the air.

Stationary

Non-moving

Unit of force

Newton

Weight

A large force of gravity that pulls things towards it, causing this force on an object.

Newton Meter

Used to measure forces.

Lift

The upward force that keeps an aeroplane in the air.

Lubricant

Used to reduce friction

Drag

Air and water resistance can be referred to as this force that pushes things back.

Deceleration

When drag is bigger than weight

Constant speed

No resultant force acting on an object.

Normal Contact Force

The force that exists between any two surfaces in contact with each other.

Tension Force

The force that acts in a direction to return the object to its original shape.

Thrust

The force that is the push of a jet engine. Acts opposite where the blast comes from.

Unpthrust

The force that allows an object to float in a fluid. When and object is under the fluid, the force points towards the top of the fluid.

Force formula

Pressure x area

Area formula

Force / pressure
