Sample Response: How do force and mass affect the
1 answer:
Answer:
Acceleration increases if force applied increases
Acceleration decreases if mass of the object increases
Explanation:
The relationship between mass, acceleration and force applied on an object is described by Newton's second law:
where
F is the net force applied
m is the mass of the object
a is the acceleration
We can rewrite the equation as
So we notice that:
1) acceleration is proportional to the force: therefore, if the force applied increases, the acceleration increases as well
2) acceleration is inversely proportional to the mass: therefore, if the mass of the object increases, the acceleration will decrease

(a) 120.8 m/s^2
The gravitational acceleration at a generic distance r from the centre of the planet is
where
G is the gravitational constant
M' is the mass enclosed by the spherical surface of radius r
r is the distance from the centre
For this part of the problem,
so the mass enclosed is just the mass of the core:
So the gravitational acceleration is
(b) 67.1 m/s^2
In this part of the problem,
and the mass enclosed here is the sum of the mass of the core and the mass of the shell, so
so the gravitational acceleration is
