Answer:
When an object is dropped, it accelerates toward the center of Earth. Newton's second law states that a net force on an object is responsible for its acceleration. If air resistance is negligible, the net force on a falling object is the gravitational force.
Hey there!

: Scientific law's would be a law that was proven and test and examined by scientist.These laws would basically be fact's, proven that what ever they say would technically be true.

: These are "theories" that are made by scientist usually hypothesis to see what law would actually be true. These "theories" are of course not true, they are not quite laws, they are experiment's that could be laws, but they're theories, thing's that are technically false.
Hope this helps you!
Balanced forces is the answer.
Answer:
a. 1.81
b. using the lap button feature
Explanation:
a. avg of the times
X = total horizontal distance = 25 ft
Y = total vertical distance = 125 ft
x = horizontal distance = 1 ft
y = vertical distance = ?
using the equation
y = (Y/X) (x)
inserting the values
y = (125/25) (1)
y = 5 ft
hence for each horizontal foot, the average height change is 5 ft
or
25 ft horizontal distance traveled = 125 ft vertical distance dropped
dividing both side by 25
25 ft horizontal distance traveled/25 = 125 ft vertical distance dropped/25
1 foot horizontal distance traveled = 25 ft vertical distance dropped
