There are three main laws of motion (force).  1: An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. 2: the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.
3: For every action, there is an equal and opposite reaction.]]> 2020-05-06 15:44:59 UTC https://padlet.com/victorfreitas/h26f3opaswm7znpb/wish/555149242 victorfreitas https://padlet.com/victorfreitas/h26f3opaswm7znpb/wish/555149661 2020-05-06 15:45:07 UTC https://padlet.com/victorfreitas/h26f3opaswm7znpb/wish/555149661 victorfreitas https://padlet.com/victorfreitas/h26f3opaswm7znpb/wish/555149818 Johnsathoniel pushed a 20kg box at 10m/s^2.
