You are standing perfectly still and then you take a step forward. Before the step your momentum was zero, but afterward you have some momentum. Is the principle of conservation of momentum violated in this case?

To determine whether the principle of conservation of momentum is violated when you take a step forward while standing still, we can analyze the situation step by step. ### Step 1: Understanding Initial Momentum Before you take a step, you are standing still. In this state, your momentum is zero because momentum (p) is defined as the product of mass (m) and velocity (v): \[ p = m \cdot v \] Since your velocity is zero, your momentum is also zero. ### Step 2: Taking a Step Forward ...

Suppose a ball of mass m is thrown vertically upward with an initial speed v , its speed decreases continuously till it becomes zero. Thereafter, the ball beigns to fall downward and attains the speed v again before striking the ground. It implies that the magnitude of initial and final momentums of the ball are same. Yet, it is not an example of conservation of momentum. Explain why?

Assertion : A bullet is fired from a rifle. If the rifle recoils freely, the kinetic energy of rifle is more than that of the bullet. Reason : In the case of rifle bullet system the law of conservation of momentum violates.

A bullet of mass 50g moving with velocity 600m//s hits block of mass 1.0kg placed on a rough horizontal ground and comes out of the block with a velocity of 400m//s . The coefficient of friction between the block and the ground is 0.25 . Neglect loss of mass of the block as the bullet pierces through it. (a) In spite of the fact that friction acts a an external force, can you apply principle of conservation of momentum during interaction of the ullet with the block? (b) Find velocity of the block immediately after the bullet pierces through it. (c)FInd the distance the block will travel before it stops.

A ballistic pendulum is a device that was used to measure the speeds of bullets before the development of electronic tiring, devices. The device consists of a large block of wood of mass M , hanging from two long cords. A bullet of mass m is fired into the block. the bullet comes quickly into rest and the block + bullet rises to a vertical distance h before the pendulum comes momentarily to rest as the ends of the arc. ltbr. In the process. the linear momentum is conserved. In such a collision. some kinetic energy is dissipated as heat: so mechanical energy is not conserved. When there is a loss in mechanical energy, the collision is said to be inelastic. Further when two bodies coalesce, the collision is said to be perfectly inelastic. The collision of block-bullet system is

STATEMENT-1 : A person standing on a stationary trolley placed on rough ground walks for a moment and then stops. The system acquires a net velocity due to this. and STATEMENT-2 : In the present situation, law of conservation of linear momentum is violated.

A proton and an alpha particle are projected in a magnetic field which exists in the width of region d. Compare the angles of deviation suffered by the proton and the alpha particle if before entering the magnetic field both the particles. a. have the same momentum, b. have the same kinetic energy, and c. are accelerated through the same potential difference. Take m_alpha = 4 m_p, q_alpha = 2 q_p.
