Question

Newtons second law of motion relates an objects acceleration to:
a) its mass
b) its velocity
C) the net force acting on it
d) Two of the above.​

Answer 1

Answer:

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Answer 2

C) the net force acting on it

• Newton’s second law: F = ma
• Newton's second law is a quantitative description of the change that a force can cause in an object's motion .
• The rate of change of an object's momentum over time is such that its magnitude and direction are equal to the force acting on the object . The momentum of an object is equal to the product of its mass times its speed .
• Momentum , like velocity , is a vector quantity that has both magnitude and direction . A force applied to an object can change the magnitude or direction of the momentum , or both . Newton's second law is one of the most important in all of these physics .
• For an object of constant mass m , we can write this as F = ma .
• where F (force ) and a (acceleration ) are vector quantities .
• When a resultant force acts on a body , it accelerates according to the equation .
• On the other hand , if the object is not accelerating , there is no net force acting on it .
