When the force acting on the body equal to acceleration?

topjm [15]

Answer:

Acceleration and velocity Newton's second law says that when a constant force acts on a massive body, it causes it to accelerate, i.e., to change its velocity, at a constant rate. In the simplest case, a force applied to an object at rest causes it to accelerate in the direction of the force.

Boy A and Boy B are pulling on a rope. If the rope is not moving toward either boy, identify two balanced forces involving the r

natima [27]

Answer:

Hey

The rope isn't moving because each boy is pulling with the same force on opposite ends. That being said the bot pulling force is balanced.

Inside the rope are molecules connecting the whole thing together. The force they exert on each other must be equal because they aren't moving but are still exerting forces

What is the kinetic energy of a 7.26 kg bowling ball that is rolling at a speed of 2m/s

vlada-n [284]

Answer:

Explanation:

The kinetic energy of an object can be found by using the formula

$k = \frac{1}{2} m {v}^{2} \\$

m is the mass

v is the velocity

From the question we have

$k = \frac{1}{2} \times 7.26 \times {2}^{2} \\ = 2 \times 7.26$

We have the final answer as

Hope this helps you

What are the two factors that determine the amount of gravitational force between two objects?

melisa1 [442]

Answer:

The mass of the objects

Distance between the objects

Explanation:

The two factors that determines the amount of gravitational force between two objects is the mass of the objects and the distance between them.

Gravitational force of attraction is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between them. This is the postulate of the newton's law of universal gravitation.

Mathematically:

F = $\frac{Gm_{1}m_{2} }{r^{2} }$

m is the mass

r is the distance

G is the universal gravitation constant
