The correct option is B. kinetic. Kinetic energy is a form of energy that is possessed by the particles by virtue of motion.

## What is constant motion in physics?

In mechanics, a constant of motion is a quantity that is conserved throughout the motion, imposing in effect a constraint on the motion. However, it is a mathematical constraint, the natural consequence of the equations of motion, rather than a physical constraint (which would require extra constraint forces).

## What does constant speed mean in physics?

Definition: When the speed of an object remains the same – it does not increase or decrease – we say it is moving at a constant speed.

## What is constant velocity motion?

A constant velocity is a velocity that does not change; it is a constant and does not vary with time. Similarly, a constant acceleration does not change with time either. Motion with constant velocity is familiar to you, since it exists any time you are driving or flying in a constant direction with a constant speed.

## Does constant motion require a force?

Constant motion requires no resultant force.

## What is non constant motion?

Definition: This type of motion is defined as the motion of an object in which the object travels with varied speed and it does not cover same distance in equal time intervals, irrespective of the time interval duration.

## Why are particles are in constant motion?

Particles on Earth move mostly because of heat. Any material has a temperature, which is related to the energy of the atoms and molecules that make it up. Due to the conservation of energy, if one particle loses energy, another gains energy.

## What is in constant motion biology?

The molecules in a gas, a liquid or a solid are in constant motion due to their kinetic energy. Molecules are in constant movement and collide with each other. These collisions cause the molecules to move in random directions.

## What is constant speed and constant velocity?

An object has constant velocity when both the magnitude and direction of the rate at which such an object is changing its position remain constant. In other words, for an object to have constant velocity its movement has to not change directions over time and the object must have constant speed as well.

## What does constant rate mean?

A rate of change is constant when the ratio of the output to the input stays the same at any given point on the function. The constant rate of change is also known as the slope. Linear functions will have a constant rate of change.

## What is constant velocity example?

A car moving at a constant speed will elapse equal distance in an equal duration of time hence is an example of constant velocity. The velocity of a car is measured as the ratio distance covered by the car from its initial position to reach a certain distance in time ‘t’.

## Is constant speed acceleration?

If speed is constant, particle may still have an acceleration. e.g. in uniform circular motion, speed is constant but as the direction of motion changes continuously, velocity changes and there is acceleration.

## What is constant acceleration?

Constant acceleration is defined as a change in velocity that does not vary over time. If a car increases its velocity by 20 mph in one minute, then another 20 mph the next, its average acceleration remains constant at 20 mph per minute.

## How do you calculate constant motion?

The equation v – = v 0 + v 2 v – = v 0 + v 2 reflects the fact that when acceleration is constant, v – v – is just the simple average of the initial and final velocities.

## What is the name of constant velocity?

These two words mean the same thing. That is, constant velocity is called uniform velocity.

## What is constant force examples?

Examples of Constant Force Gravity: Motion of an object on the surface subjected to the pull of the earth’s gravity. Cycling: Cycling can also be considered as an example of constant force. In a condition, To keep the speed of the cycle constant, it is required to apply a force in a constant manner.

## What does constant force mean?

A constant force is any force acting on an object at an unchanging rate.

## Does constant speed mean no force?

According to Newton’s first law of motion, any object moving at constant velocity has no net external force acting upon it, which means that the sum of the forces acting on the object must be zero.

## What is the difference between constant and uniform motion?

The velocity is said to be uniform if the body covers an equal distance in an equal interval of time. The velocity is said to be constant if the body moves along a straight line without changing its direction. The acceleration is zero in both cases.

## What are the types of motion?

According to the nature of the movement, motion is classified into three types as follows: Linear Motion. Rotary Motion. Oscillatory Motion.

## Why is acceleration not constant?

Since accelerating objects are constantly changing their velocity, one can say that the distance traveled/time is not a constant value. A falling object for instance usually accelerates as it falls.

## Is all matter in constant motion?

Particles in all states of matter are in constant motion and this is very rapid at room temperature. A rise in temperature increases the kinetic energy and speed of particles; it does not weaken the forces between them. The particles in solids vibrate about fixed positions; even at very low temperatures.

## Which particles are in constant motion around the nucleus?

A third type of subatomic particle, electrons, move around the nucleus. The electrons have a negative electrical charge. An atom usually contains an equal number of positively charged protons and negatively charged electrons.

## Are molecules always in motion?

Not only are molecules really small but they are in constant motion. The motion is called “thermal motion” because it’s caused by temperature. Increase the temperature around them and the molecules move faster.

## Does human body have electrons?

On grounding the body, electrons find an easy path to enter the body and perhaps able to neutralize the oxidative stress. Water is a major electron provider inside the body and let us reviews what has been reported so far in the role of water in health and disease. Water has a major role to play in all living systems.
