EX: If a big ball is rolling at a small ball with 25 newtons of force pushing it, and the small ball is exactly half of the size of the big ball and is being pushed by 50 newtons of force they will hit each other and move away from each other at the same velocity

If they are moving at speeds that will even out the amount of force they give off it will be the same

Q3: How can two objects of different masses exert the same amount of force

EX: If you have two people pushing an object from one side and they are exerting a combined force of 50 newtons, and you have two more people on the other side of the object exerting a combined force of 100 newtons the people that exert more force will be able to push back on the other people who are exerting less force.

if acted upon by multiple forces the object will be moved by the highest amount of force

Q2: In which direction will an object move if acted upon by multiple forces.

Subtopic

NEWTON'S 1ST LAW: An object will remain doing what it is doing unless acted upon by an outside force.

NEWTON'S 2ND LAW: The behavior of objects for which all existing forces are not balanced. The acceleration of an object is dependant on the variables mass and force.

NEWTON'S 3RD LAW: For every action there is an equal and opposite reaction.

EX: If a ball is rolling in a straight line down a hill, the ball will remain moving in that straight line until it is acted on by and outside force, this force could be anything from a tiny pebble to another ball running into it.

Objects will do this because if there isn't any outside forces acting upon it it can't move in another direction.

Q1:Why do objects at a constant velocity remain at that constant velocity?
