What is Acceleration?

Introduction:

Acceleration is when something changes its speed or direction.

Main Explanation:

Think of acceleration like a car pushing down on the gas pedal. It makes the car go faster, which is a change in speed. Or, think of a car turning a corner. It's changing direction, even though its speed might stay the same. That's also acceleration. Acceleration is measured in units called "meters per second squared" (m/s²). This means how many meters an object's speed changes by every second.

Acceleration can be positive or negative. Positive acceleration happens when the speed of the object increases. Negative acceleration happens when the speed decreases. For example, a rocket blasting off has positive acceleration. A car braking has negative acceleration. Acceleration is an important concept in physics because it helps us understand how objects move.

Conclusion:

Acceleration is a fundamental concept in physics that describes the change in speed or direction of an object. It's measured in meters per second squared (m/s²) and can be positive or negative. Understanding acceleration is essential for understanding how objects move and interact with each other.
