# Physics Equations

### All the Physics Equations needed for physics triple science 9-1

What is the Equation linking weight, mass and gravitational field strength Weight = Mass x Gravitational Field Strength.
What is the Equation linking work done, force & distance work done = force x distance
What is the Equation linking force applied to a spring, spring constant &extension force applied to a spring = spring constant x extension
What is the Equation linking moment of a force, force & distance moment of force = force x distance
What is the Equation linking pressure, force normal to a surface & area of that surface Pressure = force normal to a surface ÷ Area of that surface
What is the Equation linking distance travelled, speed and time distance travelled = speed x time
What is the Equation linking acceleration, change in velocity & time taken acceleration = change in velocity ÷ time taken
What is the Equation linking resultant force, mass & acceleration resultant force = mass x acceleration
