Study Notes
Motion and Acceleration
- Acceleration is calculated as the rate of change of velocity, often expressed as Δv / Δt, where Δv is the change in velocity and Δt is the time over which the change occurs.
- Acceleration is considered a vector quantity because it has both magnitude (amount of movement) and direction, which means it can be described in terms of its size and direction.
Velocity
- Velocity is defined as the rate of change of an object's position with respect to time, often expressed as displacement per unit time.
- Velocity is a vector quantity, having both magnitude (speed) and direction.
Uniform Motion
- Uniform motion refers to the motion of an object at a constant velocity, meaning the object moves at a constant speed in a straight line.
- The characteristic of an object in uniform motion is that it maintains a constant velocity, with no acceleration or deceleration.
Displacement and Velocity
- Displacement is related to velocity in that it is the total distance traveled by an object in a specific direction, whereas velocity is the rate of change of that displacement.
