Worksheet time: 7mins
Name two types of contact forces.
Friction, Tension
Pressure, Buoyancy
Inertia, Velocity
Gravity, Magnetism
What are non-contact forces? Give an example.
Electric force
An example of a non-contact force is gravitational force.
Frictional force
Magnetic force
What is the formula for calculating pressure?
Pressure = Area / Force
Pressure = Force + Area
Pressure = Force / Area
Pressure = Mass / Volume
What unit is pressure measured in?
Newtons per square meter (N/m²)
Millimeters of mercury (mmHg)
Atmospheres (atm)
Pascals (Pa)
If a force of 10 N is applied over an area of 2 m², what is the pressure?
20 Pa
2 Pa
5 Pa
10 Pa
How does increasing the area affect pressure, assuming the force remains constant?
Increasing the area decreases pressure, assuming force remains constant.
Increasing the area causes pressure to fluctuate, assuming force remains constant.
Increasing the area increases pressure, assuming force remains constant.
Increasing the area has no effect on pressure, assuming force remains constant.
What happens to pressure if the density of a fluid increases?
Pressure remains constant regardless of fluid density changes.
Pressure increases if the density of a fluid increases.
Pressure decreases if the density of a fluid increases.
Pressure is unaffected by the density of a fluid.
What is the relationship between pressure and force?
Pressure increases with decreasing force.
Force is independent of area.
Pressure is the same as force.
Pressure is the force applied per unit area.
Define atmospheric pressure and its significance.
Atmospheric pressure is the temperature of the air in the atmosphere.
Atmospheric pressure is the amount of moisture in the air.
Atmospheric pressure is the speed of wind at sea level.
Atmospheric pressure is the force exerted by the weight of air above a point, significant for weather, boiling points, and respiration.
How does pressure change with depth in a fluid?
Pressure remains constant regardless of depth in a fluid.
Pressure increases with depth in a fluid.
Pressure decreases with depth in a fluid.
Pressure fluctuates randomly with depth in a fluid.
What is the effect of temperature on the pressure of a gas?
The pressure of a gas remains constant regardless of temperature changes.
Temperature has no effect on the pressure of a gas.
The pressure of a gas increases with an increase in temperature.
The pressure of a gas decreases with an increase in temperature.
Describe how pressure is distributed in a fluid at rest.
Pressure is constant regardless of depth in a fluid at rest.
Pressure in a fluid at rest increases with depth and is exerted equally in all directions.
Pressure is only exerted vertically in a fluid at rest.
Pressure decreases with depth in a fluid at rest.
What is the principle of Pascal's law regarding pressure?
Pressure increases with depth in a fluid only.
Pressure in a fluid is dependent on the shape of the container.
Pressure applied to a confined fluid is transmitted equally in all directions.
Pressure is only transmitted in the direction of the applied force.
