Unit 8.1 Flashcard 1

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) or kilometers per hour (km/h).

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total Time.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the shortest straight-line distance from the initial to the final position, including direction.

Front

What does it mean for an object to be moving at a constant speed?

Back

An object is moving at a constant speed when it covers equal distances in equal intervals of time, regardless of the direction.

Front

How can you describe an object that is speeding up?

Back

An object that is speeding up is experiencing an increase in its velocity over time, which can be due to a change in speed or direction.

Front

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

Back

Distance can be calculated using the formula: Distance = Speed x Time.

Front

What is the significance of a dot on a motion graph?

Back

A dot on a motion graph typically represents the position of an object at a specific point in time.

Front

How do you interpret a motion graph with a horizontal line?

Back

A horizontal line on a motion graph indicates that the object is at rest, as there is no change in position over time.

Front

What is the unit of measurement for speed?

Back

The unit of measurement for speed is typically meters per second (m/s) or kilometers per hour (km/h).

What does it mean if an object has a negative velocity?

Back

A negative velocity indicates that the object is moving in the opposite direction to the defined positive direction.
