You are explaining to friends why astronauts feel weightless orbiting in the space shuttle, and they respond that they thought g
MissTica
The Earth's radius is 6371 km. So that's our distance from the center when we're on the surface.

The Shuttle astronaut's distance from the center, when s/he's in orbit, is 330 km greater ... that's 6701 km.

The force of gravity is inversely proportional to the distance between the center of the Earth and the center of the astronaut. So, in orbit, it's

(6371/6701)^2 = 90.4 %

of its value on the surface.

An object is moving in a straight line at constant speed. A resultant torce begins to act upon
alekssr [168]

Answer: The velocity magnitude or the velocity direction chages.

Explanation:

According to Newton's second law of motion, the acceleration of a system moved in same direction and is also directly proportional to the external force which acts on it while inversely proportional to the mass. The formula is: a = F/m

Based on the question, since the object obtains acceleration, then it can be infered that there will be changes in the velocity magnitude or the direction as a result of the motion.
