Isaac Newton’s investigations of gravity explained which of the following?
2 answers:
C. Gravity acts on all objects in the universe.
Explanation:
Isaac Newton with his studies understood that the force of gravity acts on all objects with mass in the universe, and it is the same force that causes an apple to fall from a tree and that keeps the Earth in motion around the Sun.
Newtons also created a formula that allows us to calculate the force of gravity between two objects:
where
G is the gravitational constant
m1 and m2 are the masses of the two objects
r is the separation between the two objects

Answer:
True
Explanation:
In this particular case, the area of the graph represents the impulse.
In fact, impulse is defined as the change in momentum of an object:
Moreover, impulse is also defined as the product between the magnitude of the force acting on an object and the duration of the collision:
If we plot a graph of the force versus the time, if the force is constant then this graph will have a rectangular shape, and the area under the graph will simply be the product
which corresponds to the definition of impulse.
