Front

What is the difference between distance and displacement?

Back

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

Front

Define velocity.

Back

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

Front

What is the formula to calculate displacement when given two perpendicular distances?

Back

Displacement = √(x² + y²), where x and y are the distances traveled in perpendicular directions.

Front

What does a positive velocity indicate?

Back

A positive velocity indicates that an object is moving in the positive direction of the chosen reference frame.

Front

What does a negative velocity indicate?

Back

A negative velocity indicates that an object is moving in the opposite direction of the chosen reference frame.

Front

If a car travels 60 km east and then 80 km north, what is the angle of displacement with respect to the east direction?

Back

The angle can be calculated using tan(θ) = opposite/adjacent = 80/60, leading to θ = arctan(4/3).

Front

What is the significance of a reference point in motion?

Back

A reference point is a stationary object used to determine the position and motion of another object.

Front

How can you determine if two objects have the same displacement?

Back

Two objects have the same displacement if they end up at the same final position from the same starting point, regardless of the path taken.

Front

What is the relationship 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 is the unit of displacement in the SI system?

Back

The unit of displacement in the SI system is meters (m).
