A student observes that for the same net force heavier objects accelerate less which statement describes the correct conclusion?

rodikova [14]

Answer: A decrease in acceleration causes the mass to increase.

Explanation:

Let's rewrite this as:

"For a constant force F, we can see that heavier objects accelerate less"

Then, as the mass increases, the acceleration of the object decreases.

This is known as an inverse relationship between acceleration and mass.

By second Newton's law we have that:

F = m*a

Force equals mass times acceleration.

So if the force is constant, we can write it as:

a = F/m.

In this equation, we can see that, if the acceleration decreases and F remains constant, then the mass m must increase (because it is in the denominator)

Then the correct option is:

A decrease in acceleration causes the mass to increase.

Example of first, second and third law of motion.

statuscvo [17]

Examples of Newton's three law of motion.

First law of motion: A rocket being launched up in the atmosphere.

Second law of motion:while riding a bicycle, a bicycle acts as a mass and our legs pushing on the pedals of the bicycle is the force.

Third law of motion:when we jump off from the boat,the boat moves backward.

A gas is confined to a vertical cylinder by a piston of mass 2 kg and radius 1 cm. When 5J of heat are added, the piston rises b

Anarel [89]

The work done by gas is 0.753 J and change in internal energy is 4.247J

So we are given that mass is 2kg , radius 1 cm and the amount of heat is 5 cm

The piston raised by 2.4cm

As we know that Work done is PΔV

Where ΔV is change in volume

Therefore ΔV = πr^2 h = π x (.01)^2 x .024 =7.53×10^(-6)m^3

Here pressure is 10^5 pa

So W = $10^5\times7.53\times10^-(6)$

Therefore W = 0.753 J

Now coming to change in internal energy

Change in Internal Energy = Heat Added - Energy lost in work

∴ 5J - 0.753 J = 4.247J

Hence the change in internal energy is 4.247 J
