Study Notes
Kinematics
- Kinematics is the study of motion without considering the cause of the motion.
- Motion is relative to an observer.
- A body in motion changes its position relative to an observer.
- A body at rest does not change its position relative to an observer.
Distance and Displacement
- Distance is the total length of the path traveled by a body.
- It is a scalar quantity, meaning it only has magnitude.
- Displacement is the shortest distance between the initial and final positions of a body.
- It is a vector quantity, having both magnitude and direction.
Speed and Velocity
- Speed is the rate of change of distance.
- It is a scalar quantity.
- Velocity is the rate of change of displacement.
- It is a vector quantity.
Acceleration
- Acceleration is the rate of change of velocity.
- It is a vector quantity.
- Average acceleration is the change in velocity divided by the change in time.
- Instantaneous acceleration is the acceleration at a specific instant in time.
Velocity-Time Graphs
- The slope of a velocity-time graph represents the acceleration of the body.
- The area under a velocity-time graph represents the displacement of the body.
- A straight line on a velocity-time graph indicates constant acceleration.
- A horizontal line indicates constant velocity.
Equations of Motion
- The equations of motion are used to describe the motion of a body experiencing uniform acceleration.
- The equations can be derived using graphical methods.
- The equations are:
- v = u + at
- s = ut + (1/2)at²
- v² = u² + 2as
Projectile Motion
- Projectile motion is the motion of an object that is projected into space and then is only subject to the force of gravity.
- The trajectory of a projectile is parabolic.
- The motion of a projectile can be analyzed by considering its horizontal and vertical components separately.
- The horizontal motion has a constant velocity and zero acceleration.
- The vertical motion has an acceleration equal to the acceleration due to gravity.
- Projectile motion equations are:
- x = ut cos θ
- y = ut sin θ - (1/2)gt²
- v = u + gt
- s = ut + (1/2)gt²
- v² = u² + 2gs
