Answer:
1.a single force called the net force .
2.Balanced Force are forces equal in magnitude and opposite in direction
3.Law of Inertia, also called Newton's first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force
4.Friction is the resistance to motion of one object moving relative to another.
5.Newton's third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction.
6. wlang number 6
7.The SI unit of force is the newto , symbol N. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg.
8.Acceleration occurs when there is a net force on an object; no acceleration occurs when the net force (the sum of all the forces) is zero.
9.The rate of change in the velocity of an object per unit time is referred as acceleration and the kind of motion is known as accelerated motion.
10.Although Isaac Newton is well known for his discoveries in optics (white light composition) and mathematics (calculus), it is his formulation of the three laws of motion—the basic principles of modern physics—for which he is most famous.
