It's false. Mass is a way of measuring how much matter an object contains, where as weight measures how hard gravity is pulling on an object. While on earth, these are typically interchangeable. However, if you were to go to Mars, your mass would stay the same, but the weight will be different. This is because you still contain the same amount of matter, but the gravity's pull will be different because the moon has a different gravitational pull than the earth. Hope this helps!
Acceleration = ms^(-1)
= 60/4
=15 ms with the power of -1
89.67J
Explanation:
Given parameters:
Mass of rock = 6.1kg
Height of fall = 1.5m
Unknown:
Potential energy = ?
Solution:
The potential energy is the energy at rest or due to the position of a body.
Potential energy is mathematically expressed as;
Potential energy = mgh
m is the mass of the rock
g is the acceleration due to gravity of the rock
h is the height of the rock
Potential energy = 6.1 x 9.8 x 1.5 = 89.67J
