Speed, Velocity, and Acceleration

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, typically measured in units like miles per hour (mi/hr) or meters per second (m/s).

Front

What is the definition of velocity?

Back

Velocity is the speed of an object in a specific direction, for example, 65 mi/hr South.

Front

What is acceleration?

Back

Acceleration is the rate at which an object changes its velocity, which can involve speeding up, slowing down, or changing direction.

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

What is the difference between speed and velocity?

Back

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

Front

If an object is moving at a constant speed, what can be said about its acceleration?

Back

If an object is moving at a constant speed, its acceleration is zero.

Front

What does a distance vs. time graph represent?

Back

A distance vs. time graph shows how distance changes over time, indicating speed and motion.

Front

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

Back

A horizontal line indicates that the object is not moving (speed = 0).

Front

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

Back

A steep slope indicates a high speed.

Front

What is the formula for calculating acceleration?

Back

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