**reduce pressure**-

**decrease**the force or increase the area the force acts on. If you were standing on a frozen lake and the ice started to crack you could lie down to increase the area in contact with the ice. The same force (your weight) would apply, spread over a larger area, so the

**pressure**would

**reduce**.

Herein, what is the formula for solid pressure?

**Pressure** is the force on an object that is spread over a surface area. The **equation** for **pressure** is P = F/A. **Pressure** can be measured for a **solid** is pushing on a **solid**, but the case of a **solid** pushing on a liquid or gas requires that the fluid be confined in a container.

Furthermore, what causes liquid pressure? **Fluid pressure** is a measurement of the force per unit area on a object in the **fluid** or on the surface of a closed container. This **pressure** can be caused by gravity, acceleration, or by forces outside a closed container. Since a **fluid** has no definite shape, its **pressure** applies in all directions.

Keeping this in consideration, why does pressure increase with depth GCSE?

**Pressure increases** as the **depth increases**. Since the particles in a liquid **are** tightly packed, this **pressure** acts in all directions. For example, the **pressure** acting on a dam at the bottom of a reservoir **is** greater than the **pressure** acting near the top. This **is** why dam walls **are** usually wedge-shaped.

What is the equation for speed?

To solve for speed or rate use the formula for speed, s = d/t which means speed equals **distance** divided by time. To solve for time use the formula for time, t = d/s which means time equals **distance** divided by speed.
