Hope this helps!!
Suppose earth is a soid sphere which will attract the body towards its centre.So, acc. to law of gravitation force on the body will be,
F=G*m1m2/R^2
but we now that F=ma
and here accleration(a)=accleration due to gravity(g),so
force applied by earth on will also be mg
replace above F in formula by mg and solve,
F=G*mE*m/R^2 ( here mE is mass of earth and m is mass of body)
mg=G*mEm/R^2
so,
g =G*mE/R^2
knives, axe ,blades and nails are examples of potential energy
or sharp objects
Answer:
Explanation:
We use the kinematics equation to solve this question:
because the ball is dropped
the acceleration is the gravity, negative because it points downwards
initial height
final height
So:
