Force and Laws of Motion
(Worksheet)
Q: Fill in the blanks with suitable choice given in brackets.
1: The product of mass and velocity of a body is called __________. (momentum/force)
2: The property by the virtue of which an object tends to remain in the state of rest or of uniform motion unless acted upon by some force is called __________. (impulse/ inertia)
3: The SI unit of _________ is kilogram meters per second i.e. kg m/s (momentum/ force)
4: Momentum is a _________ (scalar/ vector) quantity and is directed along the __________ (direction/ magnitude) of velocity.
5: The total momentum of the bullet and the gun before firing would be _________ (zero/ positive / negative) because both of them ar at rest.
6: ______ forces cannot produce motion in a body but can its shape. (Balanced / Unbalanced)
7: ______ force slows down a moving bicycle when we stop pedaling it. (Frictional / Gravitational)
8: When an object is under free fall, the Force of gravity acting on the object is a ________ force. (balanced / unbalanced)
9: _________ is the property of bodies to resist a change in their state of rest or motion. (Inertia/ Mass)
10: Newton’s _________ of motion is also known as Galileo’s law of inertia. (Ist law/ IInd Law / IIIrd Law)
11: Force is a _____ quantity. (vector/ scalar)
12: ________ always opposes motion of objects. (Force of friction/ Force of gravity)
13: Action and reaction forces act on _________ but they are equal in magnitude. (two different bodies/ same body)
