What is Acceleration? • Definition: Acceleration is the rate at which an object changes its velocity. Velocity includes both the speed of an object and its direction of motion. • Changes that cause acceleration: • Speeding up: When an object's speed increases, it's accelerating. • Slowing down: When an object's speed decreases, it's also accelerating (sometimes called deceleration). • Changing direction: Even if an object moves at a constant speed, if it changes direction, it's accelerating. Examples of Acceleration • Car starting from rest: When it begins to move, its speed increases, so it's accelerating. • Car braking: As a car slows to a stop, it accelerates (decelerates). • Turning a corner: A car moving steadily around a bend is still accelerating because its direction is changing. • A ball falling: Gravity pulls the ball downward, constantly increasing its speed, causing acceleration. How is Acceleration Measured? • Units: The standard unit for acceleration is meters per second squared (m/s²). This means that every time an object accelerates, its velocity changes by a certain number of meters per second. Formula for Acceleration Acceleration = (Final Velocity - Initial Velocity) / Time

What is Acceleration?

Definition: Acceleration is the rate at which an object changes its velocity. Velocity includes both the speed of an object and its direction of motion.
Changes that cause acceleration:
- Speeding up: When an object's speed increases, it's accelerating.
- Slowing down: When an object's speed decreases, it's also accelerating (sometimes called deceleration).
- Changing direction: Even if an object moves at a constant speed, if it changes direction, it's accelerating.
