Kinematics in Physics Kinematics is the branch of physics that studies: Motion of objects without considering the cause of motion (force). So in kinematics, we describe: How fast something...
First Law (Law of Inertia) A body remains at rest or in uniform motion in a straight line unless acted upon by an external force. Concept: Objects resist change in motion → this resistance...
Friction is a contact force that opposes the relative motion or the tendency of motion between two surfaces in contact. Types of Friction (a) Static Friction Acts when there is no relative motion. Adjusts...
