The concept of motion in physics is one of the important topics under Classical Mechanics. Did you know that everything in the universe is always moving? Even if you are completely still, you still belong to the earth which is continuously moving about its axis and around the sun. Motion means a change in the position of an object with reference to time.

Retardation is nothing but a negative acceleration. The velocity of the body may either increase or decrease. The change in velocity is known as acceleration. If the velocity of the body increases, acceleration is said to be positive. Similarly, if the velocity decreases, the acceleration is said to be negative.

The train reaching the station slows down, in this case, we can say that the train is retarding. Retardation is acceleration with a negative sign. Or the negative value of acceleration shows that the velocity of a body is decreasing.

The K.E(KINETIC ENERGY) of the object is 25 J.

So, 25=1/2 × m × (5)2

Therefore,m=2 kg.

Now, when the velocity is doubled, velocity becomes=2*5=10 m/s(ms-1)

So,

K.E.=1/2 × 2 × (10)=100 J.

Now, when the velocity is increased three times, the velocity will be=3×5=15m/s

Therefore,K.E.=1/2×2×(15)2 = 225 J.

examples.

  • Our daily activities, like walking, running, closing the door, etc. involve motion. There is a change of position of the object involved in these activities.
  • The flow of air in and out of our lungs is also an example of motion.
  • The automobiles that carry passengers from the place of pick up to the destination possess motion. In this case, the position of passengers is changed from one place to another.

Movement of any object from one position to another position with respect to the observer is called as Motion. Motion Along a Straight Line: When an object moves along a straight line, the motion of the object is called rectilinear motion.

Yogita Ingle 3 years, 6 months ago

We can define motion as the change of position of an object with respect to time. A book falling off a table, water flowing from the tap, rattling windows, etc all exhibit motion. Even the air that we breathe exhibits motion! Everything in the universe moves. We live in a universe that is in continual motion. The fundamental particle of a matter that is the atom is in constant motion too.

When body change it's position continuosly wih respect to stationary object is called motion

Ayush Kumar Gupta 3 years, 6 months ago

Motion, in physics, change with time of the position or orientation of a body. ... Motion that changes the orientation of a body is called rotation. In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).

Newton's first law of motion.A body at rest will remains at rest a body in motion will continuous in motion

Adarsh Singh 3 years, 7 months ago

Newton’s first law of motion states that “A body at rest or uniform motion will continue to be at rest or uniform motion until and unless a net external force acts on it”. Suppose a block is kept on the floor, it will remain at rest until we apply some external force to it. Also, we know that it takes us more effort or force to move a heavy mass. This is directly related to the property known as Inertia. Hence, the first law of motion is also known as the law of inertia. The second law of motion describes what happens to the massive body when acted upon by an external force.  The law states that the force acting on the body is equal to the product of its mass and acceleration. The third law of motion describes what happens to the body when it exerts a force on another body. The law states that when two bodies interact, they apply force on each other that are equal in magnitude and opposite in direction.  A force resting on a table applies a downward force equal to its weight on the table.

How does the force of gravitation between two objects change when the distance between them is reduced to half?

Ans. The force of gravitation between two objects is inversely proportional to the square of the distance between them therefore the gravity will become four times if distance between them is reduced to half.
