When a constant force affects a huge object, it causes it to accelerate, that is, to change its speed, at a constant rate.<\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt; font-family: tahoma, arial, helvetica, sans-serif;\">In the simplest case, the force acting on an object at rest causes it to accelerate in the direction of the force. However, if the object is indeed in motion it may appear that the object is speeding up, slowing down, or changing its direction depending on the direction of force, directions taken by the object, and the frame of reference in which it is moving Relative to each other.<\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt; font-family: tahoma, arial, helvetica, sans-serif;\">Mathematically, Newton&#8217;s second law can be expressed through the following equation of motion:<\/span><\/p>\n<p><span style=\"font-size: 12pt; font-family: tahoma, arial, helvetica, sans-serif;\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-737 aligncenter\" src=\"https:\/\/praxilabs.com\/en\/blog\/wp-content\/uploads\/2021\/02\/\u0646\u064a\u0648\u062a\u0646-\u0627\u0644\u062b\u0627\u0646\u064a.jpg\" alt=\"Newtons second law\" width=\"176\" height=\"145\" srcset=\"https:\/\/praxilabs.com\/en\/blog\/wp-content\/uploads\/2021\/02\/\u0646\u064a\u0648\u062a\u0646-\u0627\u0644\u062b\u0627\u0646\u064a.jpg 648w, https:\/\/praxilabs.com\/en\/blog\/wp-content\/uploads\/2021\/02\/\u0646\u064a\u0648\u062a\u0646-\u0627\u0644\u062b\u0627\u0646\u064a-300x247.jpg 300w\" sizes=\"auto, (max-width: 176px) 100vw, 176px\" \/><\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt; font-family: tahoma, arial, helvetica, sans-serif;\">where F is the resultant force, m is the mass of the object, and a is the acceleration of the body.<\/span><\/p>\n<p><span style=\"font-weight: 400; font-size: 12pt; font-family: tahoma, arial, helvetica, sans-serif;\">This relationship applies the principle of preserving the momentum, which is that when the sum of the resultant forces acting on the object is equal to zero, the momentum of the object remains constant.

It is easy to notice that after pushing a car and a truck with the same intensity, the car accelerates more than the truck. This is because the mass of the car is less than the mass of the truck.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_is_an_example_of_inertia\"><\/span><span style=\"font-size: 12pt; font-family: tahoma, arial, helvetica, sans-serif;\"><b>What is an example of inertia?<\/b><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400; font-size: 12pt; font-family: tahoma, arial, helvetica, sans-serif;\">When the bus stops suddenly, people fall forward. When the driver of a bus brakes suddenly, the lower part of the body comes to rest as the bus comes to rest, but the upper part of the body continues to move forward due to the inertia of motion. As a result, a forward force is exerted on the body and we fall in the forward direction.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Praxilabs_Virtual_Labs_in_Mechanical_Physics\"><\/span><span style=\"font-size: 12pt; font-family: tahoma, arial, helvetica, sans-serif;\"><b>Praxilabs Virtual Labs in Mechanical Physics<\/b><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400; font-size: 12pt; font-family: tahoma, arial, helvetica, sans-serif;\">Experience the future of learning with Praxilabs virtual labs in Mechanical Physics.
