Study Notes
Force and Pressure
- Force and pressure are related but distinct concepts in physics.
- Force is a push or pull that can cause an object to change its motion or shape.
- Pressure is the force per unit area, typically measured in Pascals (Pa).
Defining Force
- Force is a vector quantity that can be described in terms of its magnitude and direction.
- Force is a push or pull that can cause an object to accelerate, decelerate, or change direction.
Units of Force
- The unit of force in the International System of Units (SI) is the Newton (N).
- 1 Newton is the force required to accelerate a mass of 1 kilogram by 1 meter per second squared.
