When a train takes a turn, the passengers are thrown outwards because of-
1 acceleration of motion
2 speed of motion
3 inertia of direction
4 Both (a) and (c)
Explanation:
C Law of inertia states that, everybody continues to be in its state of rest or of uniform motion in a straight line unless compelled by some external force. There are three types of inertia- 1.Inertia of rest 2.Inertia of motion 3.Inertia of direction In this question third type of inertia that causes the passengers to be thrown outwards when the driver makes sudden turn.

Which one of following is a characteristic of force?
1 can make a stationary object to start move.
2 cannot make a moving object to increase speed.
3 can make a moving object to decrease speed.
4 can change direction of an object. [SRM JEE-2018]
Explanation:
B Force characteristics- - It is a product of the interaction between two objects - It may change the state of motion. - It can also alter the direction of a moving object. - It is a vector quantity, which means it has both magnitude and direction. - It may change the shape of the object.

Two forces of magnitude \(5 \mathrm{~N}\) and \(10 \mathrm{~N}\) act on a wooden block of mass \(2 \mathrm{~kg}\). If \(5 \mathrm{~N}\) force acts towards right and \(10 \mathrm{~N}\) force acts towards left, which one of the following statements is correct?
1 Resultant force is \(15 \mathrm{~N}\) towards left.
2 Resultant force is \(15 \mathrm{~N}\) towards right.
3 Resultant force is \(5 \mathrm{~N}\) towards right.
4 Resultant force is \(5 \mathrm{~N}\) towards left.
Explanation:
D Two forces of magnitudes, \(5 \mathrm{~N}\) and \(10 \mathrm{~N}\) act on body \(\text { Letm, } P=5 \mathrm{~N}, \mathrm{Q}=15 \mathrm{~N}\) \(10 \mathrm{~N}\) \(\mathrm{~F}_{\text {net }}=5 \mathrm{~N}-10 \mathrm{~N}=-5 \mathrm{~N}\) Resultant force is \(5 \mathrm{~N}\) toward left.

The two factors on which the momentum of a body depends are and
1 Velocity, time
2 Mass, weight
3 Mass, distance
4 Mass, velocity
Explanation:
D The momentum of a body is the product of the mass of the body and the velocity of the body. The mathematical representation of the momentum of a body is \(\text { Where, } \mathrm{p}=\mathrm{mv} \quad\mathrm{p}=\text { momentum }\) \(\mathrm{m}=\text { mass }\) \(\mathrm{v}=\text { velocity }\) Here, momentum is directly proportional to the mass and velocity of the body.
