Answer:
Gravitational field strength is the force experienced by a unit mass. Gravitational force is the amount of force acting on a body. It is the product of field strength times the mass under consideration. Gravitational pull is just a more colloquial name for gravitational force.

Answer is a.)
Given: Mass m = 70 Kg Height h = 10 m; g = 10 m/s²
Required. Gravitational Potential Energy or P.E
Formula: P.E = mgh
= (70 Kg)(10 m/s²)( 10 m)
P.E = 7,000 Kg.m²/s² or
P.E = 7,000 J
Answer:2.5 meters per second
Explanation:
10/4=2.5
ANSWER:
pascal (pa) or newton per square metre
Answer:
The period of the resulting oscillatory motion is 0.20 s.
Explanation:
Given that,
Spring constant
We need to calculate the time period
The object is at rest and has no elastic potential but it does has gravitational potential.
If the object falls then the the gravitational potential change in to the elastic potential.
So,
Where,h = distance
k = spring constant
Put the value into the formula
Using formula of time period
Put the value into the formula
Hence, The period of the resulting oscillatory motion is 0.20 s.
