What is displacement in physics?

Back

Displacement is the vector quantity that refers to the change in position of an object. It is defined as the shortest distance from the initial to the final position, along with the direction.

Front

What does the area under a velocity-time graph represent?

Back

The area under a velocity-time graph represents the displacement of the object over the time interval.

Front

Define speed in the context of motion.

Back

Speed is a scalar quantity that refers to how fast an object is moving, calculated as the distance traveled divided by the time taken.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

How do you calculate average speed?

Back

Average speed is calculated by dividing the total distance traveled by the total time taken.

Front

What is a position-time graph?

Back

A position-time graph is a graphical representation that shows the position of an object at various times, allowing for the analysis of motion.

Front

What does a horizontal line on a position-time graph indicate?

Back

A horizontal line on a position-time graph indicates that the object is at rest, as its position does not change over time.

Front

What does a steep slope on a position-time graph indicate?

Back

A steep slope on a position-time graph indicates a high speed, as the position changes rapidly with time.

Front

What is uniform motion?

Back

Uniform motion refers to motion at a constant speed in a straight line, where the object's velocity remains unchanged.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time, and it can be positive (speeding up) or negative (slowing down).
