please give me answer

Answer 1

Answer:

Newton's first law of motion states that an object at rest remains at rest and an object in motion remains in motion with the same velocity unless acted upon by what we call an unbalanced force. Let's break this law down by defining some key terms. Velocity is the speed of an object in a specified direction. An unbalanced force is an external force that changes the motion of an object. When an object is at rest or moving at a constant velocity, all the forces acting on it are balanced.

The external force of the hand will move the cup by creating unbalanced forces.

External Force Cup Example

For example, my cup of coffee is resting on my kitchen table as I make this lesson. The force of gravity pulling down is balanced by the force of my kitchen table pushing up on my cup of coffee. Now, if I am to move my coffee, I must apply an external force to disrupt the balance. Thank goodness my muscles are strong enough to apply such a force so I can enjoy my cup of coffee. Ah, now that's good joe! Newton's first law of motion is also referred to as the law of inertia. Inertia is simply the resistance to change in motion. In short, objects tend to keep doing what they are already doin

Answer 2

ANSWER:

Newton's first law of motion is , if an object is in rest will remain in rest and an object in motion will remain in motion until an external force is not applied on it.

EXPLANATION:

let's understand with an example :

Eg an wooden box is at rest so it will remain in rest until we push it so our pushing is the external force. So this is the Newton's first law of motion
