Pressure And Speed Flashcards
What is the definition of pressure?
Pressure is defined as the force of an object divided by the area of the object in contact with a surface.
What two things does pressure depend on?
1.How much force
2Surface area
What is the equation for pressure?
Pressure= Force/Area
P=F/A
What is pressure measured in?
Neutons per metres squared or neutons per centimetres squared.
What is an alternate measurement for pressure?
Pascals (Pa) where 1Pa= 1N/m squared.
What happens for a fixed area?
Pressure increases as the applied force increases.
What happens for a fixed force?
The pressure increases as the contact area decreases.
What is speed?
Speed is the distance an object moves in 1 second.
What is the calculation for speed?
Speed=Distance/Time
What is speed measured in?
m/s
What is the equation for average speed?
Total distance/Total time
