A girl moves at a constant speed in the same direction. Rephrase the same sentence in fewer words using concepts related to motion.

Force and motion acts in the same direction given example

Six particles situated at the corners of a regular hexagon of side a move at a constant speed v. Each particle maintains a direction towards the particle at the next corner. Calculate the time the particles will take to meet each other.

shows a straight, long wire carrying a current I and a rod of length l coplanar with the wire and perpendicular to it. The rod moves with a constant velocity v in a direction parallel to the wire. The distance of the wire from the centre of the rod is x. Find the motional emf induced in the rod.

Places A and B are 100 km apart on a highway. One car start from A and another from B at the same time at different speeds. If the car travel in the same direction, they meet in 5 hours, if they travel towards each other, they meet in 1 hour. What are the speeds of the two cars?

An electron and a proton are moving in the same direction and possess same kinetic energies. Find the ratio of de Broglie wavelength associated with these particles.

A small creature moves with constant speed in a vertical circle on a bright day. Does its shadow formed by the sun on horizontal plane move in a simple harmonic motion?

Three simple harmonic motions of equal amplitudes A and equal time periods in the same direction combine. The phase of the second motion is 60^@ ahead of the first and the phase of the third motion is 60^@ ahead of the second. Find the amplitude of the resultant motion.

On a frictionless surface a block of mass. M moving at a speed v collides elastically with another block of same mass M which is initially at rest. After collision the first block moves at an angle theta to its initial direction and has a speed v/3 . The second block’s speed after the collision is :
