Similarly, it also proves the direct relationship of acceleration with force. This table also explains how a change in mass only, affects force. But to clear any further confusion, let’s learn it through a table. In the previous heading, the relationship of force is explained in detail with mass and acceleration. Observing the examples of Newton’s second law of motion, you can see that force is directly affected by mass. Calculate the force.įor Zyan, Mass= 50kg and Acceleration= 0.2m/s 2 Force= (Mass * Acceleration)īy putting the given value, Force (F)= (50*0.2)= 10Nįor Zyan, Mass= 40kg and Acceleration= 0.2m/s 2 Force= (Mass * Acceleration)īy putting the given value, Force (F)= (40*0.2)= 8N And Liam is pushing at a rate of 0.2m/s 2 table of 50kg with some force. Force and mass, keeping acceleration constant:įor the second example, Zayn is pushing at a rate of 0.2m/s 2 a table of 40kg with some force.But let’s prove it through calculations.įor Zyan, Mass= 50kg and Force= 20N Force= (Mass * Acceleration)īy putting the given value, Acceleration= (Force / Mass)= (20 / 50)= 0.4m/s 2įor Liam, Mass= 50kg and Force= 15N Force= (Mass * Acceleration)īy putting the given value, Acceleration= (Force / Mass)= (15 / 50)= 0.3m/s 2įrom the calculation above, it is obvious how a change in force affects acceleration. It’s common sense that Zyan’s table will have more acceleration than Liam’s. Liam is also pushing a table of 50kg but with a force of 15N. Zayn is pushing a table of mass 50kg with a force of 20N. For force and acceleration, keeping mass constant.Let’s use it again but this time we will assume some magnitudes as well. Force (F) ∝ Mass (M) Understanding the relation through Example:Īt the start of the article, you read an example. Keeping in view Newton’s second law, we know force and mass are directly related.Ī mass of 10 kilograms requires more force to make it in comparison to a mass of 5 kilograms. Force (F) ∝ Acceleration (A) Relation between Force and Mass Small force means less acceleration and bigger force means more acceleration. When a force is applied to a body in a forwarding direction, positive acceleration is produced in the same direction.Īlong with direction, acceleration and force also affect the magnitude of each other. Acceleration and force have the same direction. Similarly, a change in acceleration directly affects the force.įorce is a vector quantity, having both magnitude and direction. If mass increases, the force will also increase and vice versa. This can be rearranged as: Force, (F) = (Acceleration * Mass) (Unit- N)Īccording to this law, force is directly proportional to the mass and acceleration of a body. This is written in mathematical form as: Acceleration, (A) = (Force / Mass) (Unit- m/s 2) The acceleration of an object is dependent upon two variables- the net force acting upon the object and the mass of the object. The second law of newton explains the relationship between force, mass, and acceleration. Issac Newton, in his book ‘Principia Mathematica’ along with other studies, gave three laws of motion. Relationship between Force, Mass, and Acceleration Weight can differ from place to place due to the gravitational force. Mass and Weight are often considered the same thing. What is a difference between weight and mass? It means mass is a natural property and cannot be altered without deforming the object. Mass does not specifically make up the size of a body.Ī tennis ball and a lead ball of the same size will have different mass. Other units include pounds, atomic mass unit etc. It is commonly measured in Kilograms which is also its SI unit. The mass of a body accounts for the physical matter a body contains. Its SI unit is meter per second per second (m/s 2). It can be positive and negative depending on the nature of change.Īcceleration is derived from velocity. And its direction comes precisely from the direction of the force. What is an Acceleration?Īcceleration is the rate of change of the velocity with respect to time.Īcceleration is also a vector quantity. One newton is equal to a kilogram meter per second square.

Sometimes forces don’t change the state but the physical form of an object. Relationship between Force, Mass, and AccelerationĪn influence on a body that causes it to change its existing state.įorce is a vector quantity and exists in different forms e.g gravitational, friction, magnetic, impact e.t.c.
