Pahelp po brainly ko makakasagot need ko ngaun ung sagot.. Bale dalawang sagutan po yan explain po ninyo ung kay newton at galileo the same questions po.
Consider an old book that slides on a table and eventually comes to a halt.
Differentiate Galileo and Newton's concept on why a moving it tends to go to a rest position.
Galileo's Concept
Newton's Concept
Questions
1. What forces are acting on
the book?
2. What is the direction of
the forces?
3. Compare the magnitude
of the force.
4. Are the forces balanced
or unbalanced?
5. When does an object
comes to its rest position?

Answer:
1. There are two forces acting upon the book. One force - the Earth's gravitational pull - exerts a downward force. The other force - the push of the table on the book (sometimes referred to as a normal force) - pushes upward on the book.
2. To find the resultant force subtract the magnitude of the smaller force from the magnitude of the larger force. The direction of the resultant force is in the same direction as the larger force. A force of 5 N acts to the right, and a force of 3 N act to the left.
3. It means size of the force. It is sum of all forces acting on a body. If 2 forces act in same direction, Magnitude of force increases. It is the sum of of both forces.
4. When the motion of an object changes, the forces are unbalanced. Balanced forces are equal in size and opposite in direction. When forces are balanced, there is no change in motion. In one of your situations in the last section, you pushed or pulled on an object from opposite directions but with the same force.
5. An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force.
