Answer:
Step-by-step explanation:
Newtons 1st law:
If you slide a hockey puck on ice, eventually it will stop, because of friction on the ice. It might also stop if a hockey player places their stick in front of it.
Newton's 2nd law:
If the mass of an object is 20 kg and it's acceleration is 5 m/s, the force acting upon it is (m*a or 20*5) 100 N.
Another example that proves that force is dependent upon mass is that if you were to move a car and a truck (that were both previously stationary) at the same speed, the car would take less force/effort to move than the truck.
Newton's 3rd law:
If a book on a table, the table is exerting a force on it that is equal and opposite to the force of gravity.
If two soccer balls of the same mass collide, one moving and one stationary, then they would both apply an equal and opposite force onto each other, causing the moving ball to stop and the previously stationary ball to move at the speed of the previously moving ball.
