Speed, Velocity, and Acceleration Vocabulary

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, regardless of direction.

Front

How does velocity differ from speed?

Back

Velocity is speed in a specific direction, while speed does not include direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

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

Back

Yes, an object can accelerate if it changes direction, even if its speed remains constant.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (final velocity - initial velocity) / time.

Front

What does it mean when we say an object is in uniform motion?

Back

An object is in uniform motion if it travels equal distances in equal intervals of time.

Front

What is the significance of direction in velocity?

Back

Direction is crucial in velocity because it determines the object's path and is essential for understanding motion.

Front

What happens to the velocity of an object when it accelerates?

Back

The velocity of an object increases or decreases depending on the direction and magnitude of the acceleration.

Front

What is an example of negative acceleration?

Back

Negative acceleration, or deceleration, occurs when an object slows down, such as a car applying brakes.

Front

How can we describe the motion of a car turning a corner?

Back

A car turning a corner is accelerating because it is changing direction, even if its speed remains constant.
