Two Dimentional Motion (2D)

Introduction Of Two Dimensional Motion

1D Motion

Give two examples of two dimensional motion.

Projectile motion is a two dimensional motion with constant acceleration. Is this statement true or false?

Projectile motion is a combination of two one-dimensional motion: one in horizontal and other in vertical direction. Motion in 2D means in a plane. Necessary condition for 2D motion is that the velocity vector is coplanar to the acceleration vector. In case of projectile motion, the angle between velocity and acceleration will be 0^@ltthetalt180^@ . During the projectile motion, the horizontal component of velocity ramains unchanged but the vertical component of velocity is time dependent. Now answer the following questions: A particle is projected from the origin in the x-y plane. The acceleration of particle in negative y-direction is alpha . If equation of path of the particle is y = ax - bx^2 , then initial velocity of the particle is

Projectile motion is a combination of two one-dimensional motion: one in horizontal and other in vertical direction. Motion in 2D means in a plane.

During the projectile motion, the horizontal component of velocity ramains unchanged but the vertical component of velocity is time dependent. Now answer the following questions: An object is projected from origin in x-y plane in which velocity changes according to relation vecv = a hati + bx hatj . Path of particle is

State in the following cases, whether the motion is one, two or three dimensional motion is one, two or three dimesional motion: (a) a dite fluing onwindy day (b) a speeding car on a long straight high way (c ) a carrom coin rebounding from the side if the board (d) a plane revolving around its star.

During the projectile motion, the horizontal component of velocity ramains unchanged but the vertical component of velocity is time dependent. Now answer the following questions: A body is projected at angle of 30^@ and 60^@ with the same velocity. Their horizontal ranges are R_1 and R_2 and maximum heights are H_1 and H_2 , respectively, then A body is projected at angle of 30^@ and 60^@ with the same velocity. Their horizontal ranges are R_1 and R_2 and maximum heights are H_1 and H_2 , respectively, then

Assertion : Projectile motion is called a two dimensional motion, although it takes place in space. Reason : In space it takes place in a plane.
