force and law of motion reasoning questions
Answers
This is your answer mate ❤️
Force:It is a push or pull on an object that produces acceleration in the body on which it acts.
S.I. unit of force is Newton.
• A force can do three things on a body.
(a) It can change the speed of a body.
(b) It can change the direction of motion of a body.
(c) It can change the shape of a body.
• Balanced forces: Forces are said to be balanced forces if they nullify one another and their resultant force is zero.
• Unbalanced forces: When two opposite forces acting on a body, move a body in the direction of the greater force or forces which brings motion in a body are called as unbalanced forces.
• First law of motion: An object remains in a state of rest or of uniform motion in a straight line unless acted upon by an external unbalanced force.
• Inertia: The natural tendency of an object to resist a change in their state of rest or of uniform motion is called inertia.
The mass of an object is a measure of its inertia.
Its S.I. unit is kg.
A body with greater mass has greater inertia.
