Front

What is the total distance David walked if he goes 3 km north and then 4 km east?

Back

7 km

Front

What is the term for the distance and direction of an object's change in position from a starting point?

Back

Displacement

Front

Which of the following represents a measurement of velocity: 16 m east, 25 m/s², 55 m/h south, or 60 km/h?

Back

55 m/h south

Front

What is the key difference between velocity/acceleration and speed?

Back

Direction

Front

If Jerry walked from home to school and then from school to park, what is his total displacement if he ends up 2 km away from home?

Back

2 km

Front

What is the definition of displacement?

Back

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

Front

How do you calculate the resultant displacement when two perpendicular distances are given?

Back

Use the Pythagorean theorem: Resultant displacement = √(a² + b²) where a and b are the two distances.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

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 starting point to the endpoint.

Front

What unit is commonly used to measure velocity?

Back

Meters per second (m/s) or kilometers per hour (km/h).
