What is the formula for calculating time?

Time can be calculated using the formula: $$t = \frac{d}{s}$$ .

What is the difference between speed and velocity?

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

What is the average speed?

Average speed is calculated as total distance traveled divided by total time taken.

What is instantaneous speed?

Instantaneous speed is the speed of an object at a specific moment in time.

How do you convert kilometers per hour to meters per second?

To convert km/h to m/s, divide by 3.6.

What is the formula for calculating acceleration?

Acceleration can be calculated using the formula: $$a = \frac{\Delta v}{t}$$ where $$\Delta v$$ is the change in velocity.

If a runner accelerates from 0 to 10 m/s in 2 seconds, what is their acceleration?

$$a = \frac{10 \text{ m/s} - 0 \text{ m/s}}{2 \text{ s}} = 5 \text{ m/s}^2$$ .

What is the effect of friction on speed?
