In nature, we rarely encounter uniform movement. Usually, the bodies change the speed of movement during their movement.
Before starting to move, the speed of the car is zero. At the beginning of the movement this speed increases. When approaching...
When we hold an item in our hand, it presses our hand downwards. The force by which the body presses the horizontal surface on which it stands is called the weight of the body.
The gravity force and the weight...
If some body is being dropped, it will start falling down towards the Earth's surface. It has been determined experimentally that all bodies have the same speed if they fall through the space that has no air. Any two...
Gravitational Interaction
Gravity is an invisible force that draws all the bodies in the Universe to each other. Solar gravity keeps the planets in their orbits. Earth's gravity 'ensures' that the Moon circulates in its orbit around the Earth. The...
They studies of movement dates since the ancient Greece. For instance, Aristotle had an opinion that the bodies moves and that movement was created as a consequence of the natural order of things, such as that the natural place...
Newton's Second Law is one of the basic laws of mechanics. And it speaks about how much acceleration a body mass m gets if the force F is affected by it. The body moves at a constant speed or...
A body lying on the ground will not run on its own. Not even a small ball on the table or the ball on the grass, will not start until a it is moved by a force. On the...
The figure shows the axis of the traveled path and the value of time in seconds.
During the movement of cars we measure the length of the road (distance) and the time of movement.
When we apply the time expressed in...
What size do we measure when a body moves? How long have we been traveling? How much far we have traveled? How fast have we arrived? The following sizes we measure when moving:
Preceeded Way - The part of the...
