Question

1.
The calculated motion of an object with respect to a reference frame is called
a. Relative motion
b. Rectilinear motion
C. Vertical motion
d. Projectile motion​

Answer 1

Explanation:

The answer is

a. Relative Motion

Answer 2

The calculated motion of an object with respect to a reference frame is called Relative motion. Relative motion can be defined as the motion of an object with respect to some other object either at rest or in movement, that is, either moving or motionless object.

• The motion of the object is not considered in reference to the surface of the earth.
• The theory while computing relative motion is the understanding that the other thing is in a static state.
• Relative motion takes in all aspects of motion, that is, velocity, speed, or acceleration.
• If we think about a person sitting in an airplane, the person seems to be at a zero velocity relative to the airplane, but in fact moves with the same velocity as that of the plane taking into account the land.
• In this motion, it is dependent on the observed by the observer-dependent on the observer’s outline of reference.
• The objects may be moving in the same or dissimilar directions with reference to each other.

Relative motion can be considered either along a straight line or in a plane, in multiple dimensions.
