Kinematics

• Displacement is the change in position between two points.
• Distance is the total length travelled by an object from one point to another.
• Velocity is speed with direction, measured as displacement over time (m/s or m/min).
• Velocity is speed with direction included.
• Acceleration is the rate at which velocity changes over time.
• Acceleration is the rate at which velocity changes, measured as change in velocity over time (m/s^2 or m/s/min).
• Speed is distance divided by time taken to travel that distance (m/s or km/h).
• Acceleration is the rate at which velocity changes, measured as change in velocity divided by time taken (m/s^2).
• The SI unit for acceleration is metres per second squared (m/s^2) or metres per second per minute (m/s/min).
• Speed is distance covered per unit time (e.g., km/h), while velocity includes both speed and direction.
• The SI unit for acceleration is metres per second squared (m/s^2) and it can be positive or negative depending on whether the object is increasing or decreasing its velocity.
