Unit 3 Test Review - Motion

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in miles per hour (mph) or kilometers per hour (km/h).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is the formula for calculating time when distance and speed are known?

Back

Time = Distance / Speed.

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 units are commonly used to measure speed?

Back

Common units for measuring speed include miles per hour (mph), kilometers per hour (km/h), and meters per second (m/s).

Front

What does it mean if an object has a constant speed?

Back

An object has a constant speed if it covers equal distances in equal intervals of time, regardless of the direction.

Front

What is instantaneous speed?

Back

Instantaneous speed is the speed of an object at a specific moment in time.

Front

What is the significance of direction in velocity?

Back

Direction is crucial in velocity because it determines the object's path and can affect the overall motion.

Front

How does acceleration relate to motion?

Back

Acceleration is the rate of change of velocity over time, indicating how quickly an object is speeding up or slowing down.
