Acceleration

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

How is acceleration calculated?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

If a car speeds up from 20 m/s to 50 m/s in 5 seconds, what is its acceleration?

Back

Acceleration = (50 m/s - 20 m/s) / 5 s = 6 m/s².

Front

What does a negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

Can an object accelerate if it is moving at a constant speed?

Back

Yes, if the object changes direction, it is still accelerating.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's acceleration is constant over time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What does a velocity-time graph represent?

Back

A velocity-time graph shows how an object's velocity changes over time.

Front

What does the slope of a velocity-time graph represent?

Back

The slope of a velocity-time graph represents acceleration.
