Answer: Force and Movement
Explanation:
The first is that the object moves. The second is that a force must act on the object in the direction the object moves.
Answer:
14.8m
Explanation:
Given parameters:
Initial speed = 17m/s
Unknown:
Maximum height = ?
Solution:
At the maximum height, the final speed will be 0m/s;
We use of the kinematics equation to solve this problem.
V² = U² - 2gH
V is the final velocity
U is the initial velocity
g is the acceleration due to gravity
H is the height
0² = 17² - (2 x 9.8 x h )
0 = 289 - (9.6h)
-289 = -19.6h
h = 14.8m

Explanation:
There exist a force of gravity between two masses. It is given by :
...........(1)
Where
G is the universal gravitational constant
m₁ and m₂ are masses
r is the distance between them
From equation (1) it is clear that the force of gravity between two masses is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
So, the gravitational force between two objects is <em><u>directly proportional</u></em> to the product of the masses of the objects
