11/6 Calculating Speed

Front

What is speed in physics?

Back

Speed is the distance traveled per unit of time, typically expressed in kilometers per hour (km/h) or meters per second (m/s).

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

What units are commonly used to measure speed?

Back

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

Front

If a cyclist travels 120 kilometers in 4 hours, what is their average speed?

Back

The average speed is 30 km/h (calculated as 120 km / 4 h).

Front

What is the average speed of a car that travels 150 kilometers in 3 hours?

Back

The average speed is 50 km/h (calculated as 150 km / 3 h).

Front

How do you convert speed from km/h to m/s?

Back

To convert speed from kilometers per hour to meters per second, divide the speed by 3.6.

Front

What is the average speed of a plane that flies 600 kilometers in 1.5 hours?

Back

The average speed is 400 km/h (calculated as 600 km / 1.5 h).

Front

What is a prokaryotic cell?

Back

A prokaryotic cell is a type of cell that lacks a nucleus and other membrane-bound organelles, typically found in bacteria.

Front

What factors can affect the speed of an object?

Back

Factors that can affect speed include the object's mass, the force applied, friction, and environmental conditions.
