Physics Pressure

Front

What is pressure?

Back

Pressure is defined as the force applied per unit area on a surface. It is measured in Pascals (Pa).

Front

What is the formula for pressure?

Back

P = F/A, where P is pressure, F is force, and A is area.

Front

How does increasing the area affect pressure?

Back

Increasing the area over which a force is applied decreases the pressure.

Front

What is the unit of pressure?

Back

The unit of pressure is Pascal (Pa).

Front

What is the relationship between force and pressure?

Back

Pressure increases with an increase in force applied to a given area.

Front

What happens to pressure if the force is doubled?

Back

If the force is doubled while the area remains constant, the pressure also doubles.

Front

What is the moment of a force?

Back

The moment of a force (torque) is the measure of the force causing an object to rotate about an axis.

Front

What is the formula for calculating the moment of a force?

Back

Moment = Force x Distance (M = F x d).

Front

If the distance is halved while the force remains constant, what happens to the moment?

Back

The moment of the force is halved.

Front

What is the effect of applying a force over a smaller area?

Back

Applying a force over a smaller area increases the pressure.
