Topic related to Forces and Newton's laws

In summary, the question is whether the force of kicking stops at the exact moment when contact with the ball is lost, or if it stops before that moment. The scenario involves a ball being kicked on Earth where there is resistance and gravity, and in space where there is no resistance or gravity.

I wanted to ask from my intuition of Newton's First law that body in motion remains in motion. Assume we kick a ball on earth, we does our force of kicking stops. I mean ultimately it comes to a stop due to resistance and gravity. Now, assume it is in space with no gravity or air. When we kick it, it will move forever but it must've been moving with some accleration at the beginning b4 moving with const. velocity. When does our force of kicking actually stop. Is it the instant we lose contact with the ball? Thanks for anyone who contributes! :)

What do you think? Can it stop after we lose contact?
No.
So, it's either at that exact moment, or before.
 

What is a force?

A force is a push or a pull that can cause an object to accelerate or change its motion. It is measured in units of Newtons (N).

What are Newton's laws of motion?

Newton's laws of motion are a set of three fundamental principles that describe the behavior of objects in motion. The first law states that an object will remain at rest or in motion with a constant velocity unless acted upon by an external force. The second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The third law states that for every action, there is an equal and opposite reaction.

What is the difference between mass and weight?

Mass is a measure of the amount of matter in an object, while weight is a measure of the force of gravity acting on an object. Mass is measured in units of kilograms (kg), while weight is measured in units of Newtons (N).

How does friction affect motion?

Friction is a force that opposes motion between two surfaces in contact. It can either slow down or stop an object's motion. The amount of friction depends on the type of surfaces and the force pressing them together.

How do forces interact with one another?

Forces can interact with one another in different ways. When two forces act in the same direction, they add together to create a larger force. When two forces act in opposite directions, they can cancel each other out. Forces can also act at different angles with respect to each other, resulting in a net force with both magnitude and direction.
