What is the difference between distance and displacement?

Back

Distance is a scalar quantity that refers to how much ground an object has covered during its motion, regardless of its starting or ending point. Displacement is a vector quantity that refers to the shortest distance from the initial to the final position of an object, including direction.

Front

Define velocity and how it differs from speed.

Back

Velocity is a vector quantity that refers to the rate at which an object changes its position, including direction. Speed is a scalar quantity that refers to how fast an object is moving, without regard to its direction.

Front

What is the formula for calculating displacement?

Back

Displacement can be calculated using the formula: Displacement = Final Position - Initial Position.

Front

If a car travels 100 meters east and then 100 meters west, what is its displacement?

Back

The displacement is 0 meters, as the car ends up at its starting point.

Front

What does it mean for an object to have a velocity of 0?

Back

An object has a velocity of 0 when it is at rest or when it returns to its original position after moving.

Front

How does direction affect displacement?

Back

Direction is crucial for displacement because it is a vector quantity. Displacement takes into account the straight line from the starting point to the ending point, including the direction of that line.

Front

What is the significance of a negative displacement?

Back

A negative displacement indicates that the final position is in the opposite direction from the initial position.

Front

How can you determine the total distance traveled if an object changes direction?

Back

To determine the total distance traveled, sum all the distances covered in each segment of the journey, regardless of direction.

Front

What is the relationship between speed and velocity?

Back

Speed is the magnitude of velocity; it tells how fast an object is moving, while velocity includes both speed and direction.

Front

What is an example of a situation where distance and displacement are not the same?

Back

If a person walks in a circle and returns to the starting point, the distance traveled is the circumference of the circle, while the displacement is 0.
