A number of forces acting on a body do not cause any change in its state of rest or of uniform motion. The forces are:

Q. When a number of forces acting simultaneously on a body bring about a change in its state of rest or of uniform motion in a straight line, then these forces acting on the body are said to be.

Q.

What are the unequal and opposite forces acting on a body, which change its state of rest or uniform motion called?

Q. Choose the correct statement(s):
Statement 1: Unbalanced forces can change the direction of motion of a body.
Statement 2: A balanced force is required to accelerate the body.
Statement 3: An object moves with a uniform velocity when balanced forces are acting on it or if there is no net force acting on it.
Statement 4: Balanced force cannot bring an object at rest to motion.

Q. Assertion :Inertia is the property by virtue of which the body is unable to change by itself, its state of rest or motion and its direction of motion is uniform
Reason: The bodies do not change their state unless acted upon by an unbalanced external force
