Understanding Force and Pressure

Force is the amount of mass in an object.

Force is the speed at which an object moves.

Force is an interaction that causes an object to change its velocity.

Force is a type of energy that can be stored.

Pressure = Force + Area

Pressure = Area / Force

Pressure = Mass / Volume

Pressure = Force / Area

Watt

Pascal

Newton

Joule

Force is directly proportional to acceleration.

Acceleration is independent of force.

Force has no effect on acceleration.

Force is inversely proportional to acceleration.

Increasing the area has no effect on pressure.

Increasing the area decreases pressure.

Increasing the area causes pressure to fluctuate.

Increasing the area increases pressure.

P = A/F

P = F/A

P = F + A

P = F * A

Deflating a tire.

Contact forces are only found in liquids; non-contact forces are only found in solids.

Contact forces are always stronger than non-contact forces; non-contact forces are weak.

Contact forces involve direct interaction; non-contact forces operate at a distance.

Contact forces can only be felt through touch; non-contact forces cannot be felt at all.

Atmospheric pressure increases with increasing altitude.

Atmospheric pressure remains constant regardless of altitude.

Atmospheric pressure fluctuates randomly with altitude.

Atmospheric pressure decreases with increasing altitude.

Friction only acts on stationary objects.

Friction has no effect on the motion of an object.

Friction increases the speed of an object.

Friction opposes motion and affects the net force on an object.
