Speed, Velocity, and Acceleration

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, typically expressed in meters per second (m/s).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What does a horizontal line on a distance vs. time graph indicate?

Back

A horizontal line indicates that the object is at rest, meaning it is not changing its position over time.

Front

What does a straight diagonal line on a distance vs. time graph represent?

Back

A straight diagonal line represents constant velocity, indicating that the object is moving at a steady speed.

Front

What does a curved line on a distance vs. time graph indicate?

Back

A curved line indicates acceleration, meaning the object's speed is changing over time.

Front

How is acceleration defined?

Back

Acceleration is the rate of change of velocity per unit of time, typically expressed in meters per second squared (m/s²).

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What does a steeper slope on a distance vs. time graph indicate?

Back

A steeper slope indicates a higher speed, meaning the object is covering more distance in less time.

Front

What is the significance of the area under a velocity vs. time graph?

Back

The area under a velocity vs. time graph represents the total distance traveled by the object during that time interval.

Front

What is uniform acceleration?

Back

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