Give two examples of objects in uniform circular motion.

What is an artificial satellite? Name any two types of artificial satellite and state their functions.

State which of the following situations are possible and give an example for each of these:

An object moving with an acceleration but with uniform speed.

What do you mean by uniform circular motion?

Name a physical quantity which (i) varies (ii) remains constant when a body moves in a uniform circular motion.

Identify the kind of motion in the following cases:  
$\left(i\right)$ A car moving with constant speed turning around a curve.
$\left(ii\right)$ An electron orbiting around a nucleus.

Is uniform circular motion an example of accelerated motion? Explain.

An artificial satellite is moving in a circular orbit of radius $36,000 \mathrm{km}$. Calculate its speed if it takes $24$ hours to revolve around the earth.
