What is the force that opposes the motion of objects sliding against each other?
Friction
Attraction
Slipperiness
Acceleration
Which law states that the pressure applied to a confined fluid is transmitted undiminished in every direction throughout the fluid?
Pascal's Law
Archimedes' Principle
Newton's Law
Boyle's Law
What is the upward force exerted by a fluid on an object immersed in it?
Floating force
Buoyant force
Submerged force
Sinkage force
What is the SI unit of pressure?
Newton
Tesla
Joule
Pascal (Pa)
Which type of friction occurs when an object moves through a fluid?
Static friction
Kinetic friction
Rolling friction
Fluid friction or viscous drag
State Pascal's Law in your own words.
Pascal's Law is about the relationship between temperature and pressure in fluids.
Pascal's Law states that pressure in a fluid decreases with depth.
Pascal's Law only applies to gases, not liquids.
Pascal's Law states that a change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container.
What is the formula to calculate pressure?
Pressure = Volume / Area
Pressure = Mass * Acceleration
Pressure = Density / Volume
Pressure = Force / Area
How does the buoyant force on an object change when it is fully submerged in a fluid?
The buoyant force becomes zero
The buoyant force increases
The buoyant force decreases
The buoyant force remains the same.
What is the force that acts opposite to the direction of an object's motion?
Friction
Gravity
Inertia
Momentum
Explain how the surface area of an object affects the pressure it exerts on a surface.
Objects with larger surface areas exert less pressure
The surface area of an object affects the pressure it exerts on a surface by distributing or concentrating the force over a larger or smaller area respectively.
The surface area of an object has no impact on the pressure it exerts
The pressure exerted by an object is solely determined by its weight
