Question

State whether the following statement is true or false, and if false, write the correct statement:
Planets revolve in orbits with constant velocity.

• A. True
• B. False

Answer 1

The correct option is B False

The given statement is false.

In a perfectly circular orbit a planet has perfect tangential velocity. But in reality planet orbits are not perfectly circular and are instead elliptical. In elliptical orbit the speed will vary with the lowest speed when it is further away from the centre of the orbit and greatest speed when it is closest. Hence planets does not revolve in orbits with constant velocity.
