You are pushing a rock along level ground and making the rock speed up. How does the size of the force you exert on the rock com
Aneli [31]

Answer:

The forces are of the same magnitude just opposite directions

Explanation:

Newton's Third law tells us that if body A exerts a force on body B, then B exerts an equal but opposite force on body B. so as you continue to push the rock causing it to accelerate, the rock also continues to push back at you by an equal force in the opposite direction.

Which change will cause the gravitational force between a baseball and a soccer ball to increase? Select three options. Moving t
almond37 [142]

The three options are 1,3 and 5 Moving the balls closer together. The distance decreases and forces increase.

<h3>What is the gravitational force?</h3>

The gravitational force ia s type of force has the ability attracts any two objects with mass. Gravitational force tries to pull two masses towards each other.

The value of the gravitational force is given by;

F_g=\frac{ Gm_ 1m_2}{r^2}

It is observed that the gravitational force is directly propotional to the product of mass and inversly propotional to the square of the distance between them.

So, the correct options are :

(1) Moving the balls closer together. The distance decreases and forces increase.

(3) Wrapping the soccer ball in layers of duct tape will also increase force because the mass will increase.

(5) Similarly, putting the baseball in a plastic case will increase mass, and hence force increases.

Hence the three options are 1,3 and 5.

To learn more about the gravitational force refer to the link;
