Name: ____________________________________________

1.              Fill in the blanks:

a    Magnitude of two forces can be compared by measuring the __________________

produced by them.

b    The acceleration produced in a body of given mass is ________________________

to the ____________________ applied on it.

c    The force needed to produce a given __________________ is ____________________

_________________ to the ____________________ of the body.

d    If a _________ acting on a body of mass _________ produces an ________________

of _________________ in it, the force is said to be _____________________________

e    If two bodies of different masses are moving with the ________________ velocity, the force needed to stop the _________________ body will be _____________

f     If two bodies of same masses are moving with _____________________ velocities, the force needed to stop the ___________moving body will be _____________ than the ______________ one.

g    Force needed to stop a moving body depends on its __________ and ___________

h    The rate of change of ________________of a body is ________________________ to the ________________ applied on it and the change in ___________________ is in the direction in which the ____________________ is applied.

i     When a _________________ is applied on a moving body its ___________________

changes. Due to change in its _______________________, its ___________________

will also change.
