Which factors are used the calculate the kinetic energy of an object? Check all that apply. gravity velocity volume mass height

Answers

Answer 1

Answer: The factors that are included in the calculation of the kinetic energy of an object would be the velocity and its mass. The kinetic energy's formula is half of the product of the mass and the velocity that is squared. The volume, height, and gravity are not included.

Answer 2

Answer: Kinetic energy = (1/2) (the object's mass) (its speed or velocity)² .

No other quantities are involved.

The strength of the force of gravity depends ona. the masses of the objects and their speeds.
b. the masses of the objects and the distance between them.
c. the weight of the objects and their speeds.
d. the masses of the objects and their weights.

Answers

The correct answer to the question is : B) The masses of the objects and the distance between them.

EXPLANATION :

Before going to answer this question, first we have to understand Newton's law of gravitation.

As per Newton's law of gravitation, everybody in the universe attracts every other body with a force called gravitational force or force of gravity which is directly proportional to the product of masses of the two bodies, and inversely proportional to the square of separation distance between them.

Let us consider two bodies of masses M and M' which are separated by a distance R.

The gravitational force acting between them is calculated as -

Gravitational force $F=\ G(MM')/(R^2)$

Here, G is known as universal gravitational force constant.

From above, we see that force of gravity depends on the masses of the objects and the distance between them.

The strength of the forces of gravity between two objects is completely
determined by their masses and the distance between them.

Their speeds have no effect on the gravitational force, and their weight
IS the gravitational force.

What does trajectory mean?

Answers

Trajectory means the path that something follows.

It's almost always used to describe things that are dropped, thrown, or shot,
like the trajectory of baseballs, golf balls, and canon balls, or other things moving
under the influence of gravity, like comets, asteroids, and planets. But it doesn't
have to be the path of something sailing overhead from one place to another.
You'll also hear about a person's 'trajectory through life'.

A trajectory is the path that a moving object follows through space as a function of time. The object might be a projectile or a satellite
