11/4 Speed

Front

What is the formula to calculate speed?

Back

S = d/t, where S is speed, d is distance, and t is time.

Front

If a runner completes a 440 meter race in 45 seconds, how do you calculate their speed?

Back

Speed is calculated by dividing the distance (440 meters) by the time (45 seconds), resulting in 9.8 m/s.

Front

What is the speed of a runner who completes a 200 meter dash in 20 seconds?

Back

The speed is calculated as 200 meters divided by 20 seconds, resulting in 10 m/s.

Front

What units are commonly used to express speed?

Back

Speed is commonly expressed in meters per second (m/s) or kilometers per hour (km/h).

Front

What is the difference between prokaryotes and eukaryotes in terms of cellular structure?

Back

Prokaryotes do not have a nucleus, while eukaryotes have a defined nucleus.

Front

What is the significance of the speed formula S = d/t in real-world applications?

Back

This formula allows us to determine how fast an object is moving, which is essential in fields like physics, engineering, and sports.

Front

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

Back

To convert from m/s to km/h, multiply the speed in m/s by 3.6.

Front

What factors can affect a runner's speed?

Back

Factors include physical fitness, running technique, terrain, and environmental conditions.

Front

In the context of speed, what does 'd' represent in the formula S = d/t?

Back

In the formula, 'd' represents the distance traveled by the object.

Front

What does 't' represent in the speed formula S = d/t?

Back

In the formula, 't' represents the time taken to travel the distance 'd'.
