Answers
Answer:
❝In physics, the motion is the change in position of an object with respect to its surroundings in a given interval of time.❞
The motion of an object with some mass can be described in terms of the following:
➣Distance
➣Displacement
➣Speed
➣Velocity
➣Time
➣Acceleration
Types of Motion
Motion of an object depends on the type of force acting on the body.
❥ Translational – It is the type, where an object moves along a path in any of the three dimensions.
❥ Rotational – It is the type, where an object moves along a circular path about a fixed axis.
❥Linear – It is a type of translational motion where the body moves in a single direction along a single dimension.
❥ Periodic – It is the type of motion that repeats itself after certain intervals of time
❥ Simple Harmonic – It is the type of motion like that of a simple pendulum where a restoring force acts in the direction opposite to the direction of motion of the object. This restoring force is proportional to the displacement of the object from mean position.
❥ Projectile – It is the type of motion which has a horizontal displacement as well as vertical displacement.
❥ Oscillatory – It is the type of motion which is repetitive in nature within a time frame. If it is mechanical in nature it is called vibration.

Answer:20
Step-by-step explanation:by anglesum property of triangle
sum of angles of triangle =180*
(x-10)+(2x+10)+6x=180
x+2x+6x-10+10=180
9x=180
x=180/9=20
