Due to inertia, every object stays at rest or moves with uniform velocity. Assume that any object that moves had been at rest at some time earlier.
A body is imparted motion, ie., is given a velocity. As per Newtons' 1st law, there must be an unbalanced, net resultant force acting on it, to change the objects state of inertia to an accelerating state.

The motion imparted to objects is due to thea)Action of weightb)Action...
The correct answer is D) Action of force.
Explanation:
Motion is the change in position of an object with respect to its surroundings. It can be caused by various factors, but the main reason behind the motion of objects is the action of force.
Force is a push or pull acting on an object. When a force is applied to an object, it can cause a change in the object's motion. This change can be in the form of starting the motion of a stationary object, stopping the motion of a moving object, or changing the direction or speed of a moving object.
Force can be exerted on an object in different ways, such as through contact forces or non-contact forces. Contact forces involve direct physical contact between objects, while non-contact forces act at a distance.
Examples of contact forces that can cause motion include:
1. Pushing a car: When a person pushes a car from behind, a force is exerted on the car in the forward direction, causing it to move.
2. Kicking a football: When a football player kicks a ball, the force of the player's foot against the ball causes it to move.
Examples of non-contact forces that can cause motion include:
1. Gravitational force: The force of gravity pulls objects towards the center of the Earth. When an object is dropped, the force of gravity causes it to fall downward.
2. Magnetic force: The force of attraction or repulsion between magnets can cause objects to move. For example, when two magnets with opposite poles are brought close to each other, they exert a force on each other, causing motion.
In conclusion, the motion imparted to objects is due to the action of force. Force can be exerted through contact forces or non-contact forces, such as gravity or magnetism. It is the force acting on an object that causes a change in its motion.
