Study Notes
Linear Motion
- Uniform motion has a constant velocity and zero acceleration.
- The mathematical description of position x as it varies with time t for linear motion is x(t) = x0 + vt, where x0 is the initial position and v is the velocity.
Newton's First Law of Motion
- Objects that do not experience any net force remain in their state of motion or rest.
Factors Affecting Motion
- Friction and air resistance can cause an object to change the direction of its motion under everyday circumstances.
Types of Linear Motion
- Rectilinear motion is the type of motion exhibited by an athlete running a 100-meter dash along a straight track.
