Explanation:
The energy stored in an elastic objects as a result of deformation is called elastic potential energy. The energy stored in a spring is given by :
Where
k = spring constant
x = compression or stretching in an spring
While gravitational potential energy is given by :
PE = mgh
where
m = mass
g = acceleration due to gravity
h = height from ground
So, the factor affecting elastic potential energy but not gravitational potential energy is " spring constant ".
Answer:
By applying a force of one Newton, one can hold a body of mass of 102 gram.
Explanation:
- Force is the pull or push of an object. It can be mathematically measured as, F= m* g.
where, F= force in newton
m= mass in kg
g= acceleration due to gravity ( )
- For 1 newton force,
F= m* 9.8
or, m= = 0.102 kg
or, m= 102 gram.
- Hence, 102 gram mass can be hold by one Newton force.
