If an object has kinetic energy, what must it be doing?

Answers

Answer 1

Answer:

It has to be moving in order for it to be kinetic energy and potential energy is when is not moving.

Answer 2

Answer:

The Object Must Be Moving!

Explanation:

Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed.

NASA plans to launch a new satellite to orbit the Earth. As the satellite is launched the thrust of the hot exhaust gas is pushed through the rocket nozzle and is accelerated toward the rear of the rocket.

A The downward force exerted by the exhaust on the engine is greater.
B The magnitude of both forces is equal to zero acting in opposite directions.

A ball bounces on the ground. How do the ball and the ground act on each other?(1 point)

A. The ball exerts a stronger force than the ground but in the same direction.

B. The ball and the ground exert forces on each other with equal magnitude and in the same direction.

C. The ball and the ground exert forces on each other with equal magnitude but in opposite directions.

D. The ball exerts a stronger force than the ground and in the opposite direction.

Answers

I believe it is A your welcome

If a ball bounces on the ground, Then the ball and the ground exert forces on each other with an equal magnitude but in opposite directions. The correct option is C.

What is Newton's third law of motion?

Newton's third law of motion, also known as the law of action and reaction, states that for every action, there is an equal and opposite reaction. This means that whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object.

In other words, forces always occur in pairs. When you push on a wall, for example, the wall pushes back on you with an equal force in the opposite direction. This is why you don't fall through the wall when you push on it.

This law applies to all objects, regardless of their size or speed. It is one of the fundamental principles of physics and is used to explain many everyday phenomena, such as why a balloon moves forward when air is expelled from it or why a boat moves forward when it pushes water backward.

Newton's third law of motion is important in many fields of science and engineering, including mechanics, aerodynamics, and rocket science. It plays a key role in the design and operation of many machines and devices, from cars and airplanes to rockets and satellites.

Here in the Question,

When a ball bounces on the ground, the ball exerts a downward force on the ground due to its weight. This force causes the ball to compress and deform slightly as it collides with the ground. At the same time, the ground exerts an equal and opposite force on the ball, known as the normal force. This force pushes the ball upward and causes it to rebound from the ground.

According to Newton's third law of motion, for every action, there is an equal and opposite reaction.

So, the force exerted by the ball on the ground is equal in magnitude but opposite in direction to the force exerted by the ground on the ball. This is why the ball bounces back up into the air after colliding with the ground.

Therefore, the ball and the ground act on each other with equal and opposite forces.

Answer:

When a substance is heated, it gains thermal energy. Therefore, its particles move faster and its temperature rises. When a substance is cooled, it loses thermal energy, which causes its particles to move more slowly and its temperature to drop.

What landform is created when an oceanic plate and a continental plate converge?

Answers

ocean trenches, island arches, faults , and volcanoes are created

Ocean trenches is created when an oceanic plate and a continental plate converge.

What is Ocean trenches?

Where a continental and oceanic plate converge or where two oceanic plates converge are the two types of convergent plate borders where ocean trenches emerge. At an oceanic/oceanic border, whichever plate is denser—the older, colder plate—subducts beneath the other because oceanic plates are denser than continental plates.

The subduction creates an underwater trench in both situations. The deepest parts of the ocean are located within these trenches, which are long, narrow valleys. The Marianas Trench, which extends approximately 36,000 feet below sea level, is the deepest ocean trench.

Hence, ocean trenches is created when an oceanic plate and a continental plate converge.
