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

Define speed.

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is velocity?

Back

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

Front

Explain the difference between speed and velocity.

Back

Speed is a scalar quantity (only magnitude), while velocity is a vector quantity (magnitude and direction).

Front

What does it mean for an object to move toward the starting point?

Back

It means the object is moving in the opposite direction from where it initially started.

Front

If a cart moves 24 m away from the starting point in 3 seconds, what is its speed?

Back

Speed = Distance / Time = 24 m / 3 s = 8 m/s.

Front

What is the formula for calculating average speed?

Back

Average Speed = Total Distance / Total Time.

Front

What is the significance of direction in motion?

Back

Direction determines the velocity of an object and affects how we describe its movement.

Front

How do you calculate displacement when an object moves back and forth?

Back

Displacement is calculated as the final position minus the initial position, regardless of the path taken.

Front

What is a scalar quantity? Give an example.

Back

A scalar quantity has only magnitude. Example: Speed.
