Questions and Answers

What is the difference between speed and velocity?

Speed is the rate at which an object covers distance, while velocity is the rate at which an object covers distance in a specific direction.

What is the SI unit for speed?

The SI unit for speed is meters per second.

How is average speed calculated?

The average speed of an object is calculated by dividing the total distance traveled by the total time taken. The equation for average speed is: $average\ speed = \frac{total\ distance},{total\ time}$.

How can we calculate the average velocity?

By drawing a line between two points in time and finding the slope of that line. Signup and view all the answers

What is the difference between average speed and average velocity?

Average speed is a scalar quantity that measures the total distance traveled divided by the total time taken. Average velocity is a vector quantity that measures the displacement (change in position) divided by the total time taken. Signup and view all the answers

How can we calculate average velocity?

Average velocity can be calculated by dividing the change in position (displacement) by the change in time. Signup and view all the answers

What is the difference between average velocity and instantaneous velocity?

Average velocity is the overall velocity over a certain period of time, while instantaneous velocity is the velocity of an object at a specific moment in time. Signup and view all the answers

How can we determine an object's velocity from a position-time graph?

We can determine an object's velocity from a position-time graph by finding the slope of the line. The slope represents the rate of change of position with respect to time, which is the velocity. Signup and view all the answers
