Which causes an object in motion to stay in motion?
A) friction
b) gravity
C) inertia
D) velocity
Its not friction..
its (c)-inertia
its ineria - c
its c
The correct answer is C) inertia.
In order to understand why inertia causes an object in motion to stay in motion, let's break down the question:
Inertia refers to the tendency of an object to resist changes in its state of motion. It is one of the fundamental principles of physics, first described by Sir Isaac Newton in his laws of motion.
According to Newton's First Law of Motion, also known as the law of inertia, an object at rest tends to stay at rest, while an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an external force.
So, in the case of an object in motion, inertia is what keeps it moving. Even without any external force acting on it, the object will continue to move at a constant velocity, as stated by Newton's law of inertia.
Friction, as mentioned in option A, actually acts in the opposite way. Friction is a force that opposes motion, and it tends to slow down or stop objects in motion.
Gravity, mentioned in option B, is the force of attraction that exists between any two objects with mass. Gravity itself does not keep an object in motion. Although gravity can influence an object's trajectory, it is not the primary factor responsible for its continued motion.
Velocity, mentioned in option D, describes both the speed and direction of an object's motion. While velocity is related to an object in motion, it does not directly cause the object to stay in motion.
Therefore, the correct answer is C) inertia, according to Newton's First Law of Motion.
