Motion 12/2

Front

What is velocity?

Back

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

Front

How is speed calculated?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance/Time).

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

What does it mean for an object to be in motion?

Back

An object is in motion if its position changes relative to a reference point.

Front

What is a reference point?

Back

A reference point is a place or object used for comparison to determine if another object is in motion.

Front

Calculate the speed of a car that travels 150 km in 3 hours.

Back

Speed = 150 km / 3 hr = 50 km/hr.

Front

If a person walks 100 meters north and then 100 meters south, what is their displacement?

Back

The displacement is 0 meters, as they end up at the starting point.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the straight line distance from the start to the end point.

Front

What is the formula for calculating average velocity?

Back

Average velocity = Total displacement / Total time.

Front

If a train travels 500 km north in 2 hours, what is its velocity?

Back

250 km/hr north.
