Question

the state of motion of an object depends on
a) the observer
b) it is a combined property of the observer and the body which is being observed
c) the.body which is being observed
d) all of the above
​

Answer 1

Answer:

The state of motion of an object is defined by its velocity - the speed with a direction.

all of above............

Answer 2

(d). The state of motion of an object depends on "The inertia of a moving object depends on the mass of the object.

The motion of an object depends on:

• The velocity of an object determines its state of motion - its speed about its direction.
• As a result, inertia may be rephrased as follows.
• An object's tendency to resist changes in velocity.
• Unless it is acted upon by an unbalanced force.
• Such an item will not change its state of motion.

Speed and direction motion:

• An object's speed and direction of motion describe its state of motion.
• Rest is the condition of motion for a body that has zero speed.
• The state of motion is a uniform motion for a body moving at a constant pace.
