Answer:
2)No
3a)Forces that are equal in size but opposite in direction is called balanced forces.Forces that cause a change in motion of objects are called unbalanced forces.
b)A contact force is a force applied to a body by another body that is in contact with it.A non contact force is a force which acts on an object without coming physically in contact with it.
4)As the ball is thrown upwards, it's speed decreases.velocity of ball is in upward direction but the acceleration is in the downward direction. since velocity and acceleration is in the opposite direction speed decreases.
hey mate !!
2)NO it is not possible because
a net non -zero force means
that there will be no. acceleration on the body and when acceleration is zero than F also be zero . so it can have non - zero velocity in any direction
☆3) balanced force:
if a set of forces acting on a body produce no acceleration in it , the forces are said to be
balanced forces.
☆unbalanced forces :
if a set forces produce a non zero acceleration, the forces are said to be unbalanced forces.
☆contact forces:
when a body A is in contact of another body b then A can exert a force on B and B Can exert a force on A is called contact forces .
☆Non contact forces :
A force which acts on an object without coming physically in contact with it .
