What is displacement in physics?

Back

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

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken. Formula: Average Speed = Total Distance / Total Time.

Front

What is the difference 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

If a student returns to their starting point, what is their displacement?

Back

The displacement is 0 meters, as the initial and final positions are the same.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

How do you interpret a distance-time graph?

Back

The slope of a distance-time graph represents speed. A steeper slope indicates a higher speed, while a flat line indicates no movement.

Front

What is average velocity?

Back

Average velocity is the total displacement divided by the total time taken. It is a vector quantity.

Front

What units are commonly used to measure speed?

Back

Common units for speed include meters per second (m/s), kilometers per hour (km/h), and miles per hour (mph).

Front

How can you determine if an object is accelerating?

Back

An object is accelerating if its velocity is changing over time, which can be indicated by a change in speed or direction.

Front

What is the significance of the slope in a speed-time graph?

Back

The slope of a speed-time graph represents acceleration. A positive slope indicates acceleration, while a negative slope indicates deceleration.
