# IIT JEE / PMT Test Series : Module 3 : +1 : Physics : Laws of Motion

Normal type of MCQ with one correct option Passengers standing in a bus are thrown outwards when the bus takes a sudden turn. This happens because of :
Outwards pull on them
Inertia
Change in momentum
Change in acceleration

24.5 N
2.45 N
79 N
73.5 N.
Normal type of MCQ with one correct option A long horizontal rod has a bead which can slide along its length, and initially placed at a distance L from one end A of the rod. The rod is set in angular motion about A with constant angular acceleration(. If the coefficient of fiction between the rod and the bead is (, and gravity is neglected, then the time after which the bead starts slipping is
Infinitesimal.
Normal type of MCQ with one correct option To avoid slipping while walking on ice one should take smaller steps because of the:
Larger friction
Larger normal reaction
Smaller friction
Smaller normal reaction


C,D
A,B,C & D
Comprehension Physics problems can be solved by using of conservation of energy. When no external force acts on the system then linear momentum is constant and conserved. The concept of momentum is used in describing objects in motion. For conservation of linear momentum only requirement is that the force must be internal to system. Impulse is the product of force and small time interval. It is equal to change of linear momentum. Conservation of linear momentum is valid for all types of collision, rocket propulsion etc. A body is projected with velocity ( and angle of projection is (. At highest point it is split into two fragments. Then:
Linear momentum is conserved only at highest point
Linear momentum is conserved only in horizontal direction
Linear momentum is conserved in only vertical direction
At any arbitrary point

Impulse is the product of force and small time interval. It is equal to change of linear momentum. Conservation of linear momentum is valid for all types of collision, rocket propulsion etc. A shell is projected withy velocity ( and angle of projection of (. At highest point it is split into two fragments. Ratio of their masses is 1 : 2. Heavy part retraces its path. The speed of other fragment is:
Assertion(Reason A. When static friction is involved mechanical energy is not conserved R. Friction is non conservative force
Both A and R are true and R is correct explanation of A
Both A and R are true and R is not correct explanation of A
A is true, R is false
A is false, R is true

Conservation of linear momentum is valid for all types of collision, rocket propulsion etc. A lighter body and heavier body both are moving with same K.E., Then:
Linear momentum of lighter body is lesser.
Linear momentum of lighter body is greater
Both have same momentum
Both have unequal momentum
