Flashcards
Kinematics
Kinematics
The branch of physics that describes the motion of points, bodies (objects), and systems of bodies without considering the forces that cause them to move.
Speed
Speed
The rate at which someone or something moves or operates.
Friction
Friction
The force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
Study Notes
Kinematics
- The study of motion is known as kinematics.
Measurement of Motion
- Speed is a measure of the rate of motion, quantifying how fast an object is moving.
Friction
- Friction is the force that resists the relative motion of two surfaces in contact.
