Is the motion of a body uniform?
In Physics, uniform motion is defined as the motion, wherein the velocity of the body travelling in a straight line remains the same. When the distance travelled by a moving thing, is same at several time intervals, regardless of the time length, the motion is said to be uniform motion.
What type of motion is observed by the body when it goes around the sun with constant speed in circular orbit uniform motion or accelerated motion *?
Answer. when a body goes round the sun with constant speed it is uniform circular motion but as it changes direction while moving in a circular orbit it is also accelerated motion ..
What is the difference between uniform velocity and non uniform velocity?
❂ When a body covers equal distance in equal interval of time in a specific direction is said to have uniform velocity. ❂ When a body covers unequal distance in equal interval of time in a specified direction is said to have non-uniform velocity.
Is a satellite moving around the Earth in a circular orbit accelerated explain?
The orbit is actually elliptical, but it is treated as circular for easier calculations. The satellite is orbiting with constant speed. The satellite’s velocity is always changing. The satellite is accelerating, because there is a net force acting on it.
Why is it important to give a satellite a horizontal speed when placing it in orbit?
To avoid hitting the Earth, an orbiting projectile must be launched with a horizontal speed of 8000 m/s. When launched at this speed, the projectile will fall towards the Earth with a trajectory which matches the curvature of the Earth.
Why would a crash affect the motion of a satellite?
Crashing into the asteroid would cause the satellite to slow down, stop, or reverse direction, because it is a force in the opposite direction to the satellite’s motion. Whichever crash was a stronger force would cause it to change motion more. Whichever crash was a stronger force would cause it to change speed more.
