Force = Mass x Acceleration. Google it if you want a more in depth explanation.
Newton's laws are applicable in a Newtonian inertial frame of reference because these laws were specifically formulated based on the assumption that the frame of reference is inertial. In an inertial frame, a body remains at rest or moves with constant velocity unless acted upon by an external force (1st law), the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (2nd law), and for every action, there is an equal and opposite reaction (3rd law). These laws provide the foundation to predict and understand the motion of objects in inertial frames.
1st law gives us an idea that a body is subject to the principle of inertia of rest, motion or direction. 2nd law, being the most important of the three, helps us to deduce the equation:F=ma 3rd law is perhaps the most popular law, "Every action has an equal and opposite reaction."
Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. In equation form, this is written as F = ma, where F is the net force, m is the mass of the object, and a is the acceleration of the object.
If Newton's second law didn't exist, we wouldn't have a quantitative relationship between force, mass, and acceleration. This law is fundamental in explaining how objects move under the influence of forces. Without it, our understanding of motion and the principles of physics would be significantly different.
To accelerate a 70kg object at a rate of 4.2 m/s^2, you would need a force of 294 Newtons. This is calculated using Newton's second law, F = m*a, where F is the force, m is the mass of the object (70kg), and a is the acceleration (4.2 m/s^2).
the 2nd one
Newton's 2nd law is F=ma.
-- There are two other laws in the set ... one before it and one after.
Newton's 2nd Law - Impulse and momentum Newtons third law - Free body diagram
take a look at newtons 1st and 2nd laws. Basically if a force is applied on an object in one direction and no other forces are present it will accelerate or decelerate.
yellow'2nd green
newtons 2nd law states that if a force is put on an object then the object will move in the oppisite direction of the force no thats the third law
because it just does
law of inertia F=MA
Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
2nd law of motion
Newtons laws have to do with lacrosse when (in guys lacrosse) you push the other player, which relates to newtons 2nd law, the larger the mass the harder the acceleration. Also, newtons 1st law involves throwing and catching a ball, newtons law says and object in motion will stay in motion until acted upon by an outside force. The object in motion is the ball and the outside force is the other person catching it, stopping the motion. Newtons third law relates to lacrosse when you make a shot and hit the post causing it to bounce off. The 3rd law states for every action theres an equal and opposite reaction. The reaction is the ball flying off the post.
