Question

define rectilinear motion, motion in plane, projectile motion ?​

Answer 1

Answer:

Rectilinear motion - When the acceleration acting on a body is always directed parallel to its initial velocity, the speed of the body changes but its direction remains unaltered. Such a motion of an object is called the linear motion.

Motion in a plane - When the direction of the acceleration acting on a body is different from the direc- tion of its initial velocity, both the speed and direction of the body exhibit a variation in their magnitudes and the body starts moving on a curved path in a plane. Such a motion is called the motion in a plane.

Projectile motion - It is merely a form of motion in plane. If an object is projected in a direction other than the vertical, it exhibits a motion in a vertical plane under gravity. This is called a projectile motion. As, the motion of a ball thrown obliquely near the earth's surface, or the motion of a bomb dropped from an aeroplane The path of a projectile motion is called trajectory A trajectory is parabolic in shape.

Answer 2

$\huge{Heya}$

Answer

Rectilinear motion

Rectilinear motion is another name of straight line motion this type of motion describe the movement of a particle are a body a body said to experience rectilinear motion if any two particles of straight lines.

Motion in plane

-----------------------

Motion in plane is the motion which includes thread motions

1⃣ Linear motion.

2⃣ Rotational motion

3⃣ Projectile motion

Projectile motion

-------------------------

Projectile motion is a form of motion experiences by an object or particle that is thrown near the Earth's surface and moves along a curved path under the motion is a form of motion experiences by an object or particle that is thrown near the Earth's surface and moves along a curved path under the action of gravity only.
