it is the property of a body by virtue of which it remains or tends to remain in the state of unifrom motion in a straight line unless unbalanced forces iact upon it
this object that appears to stay in place is a reference point.
Velocity is negative in a moving object when the object is moving in the opposite direction of its positive reference point.
it means an object is moving based on the force of friction and gravity.
Kinetic energy
The friction of a non-moving object is called static friction. It is the force that prevents the object from moving when a force is applied to it.
The resistance of an imposing object to change it's movement. Intrinsic to mass,it is present in the absence of gravity.
because gravity of the sun kicks in and makes them go faster but they do not get pulled into the sun and burn up because of inerta, ( the tendny of a stainry object to stay in place and a moving object to remain in motion unless acted upon by an outside force They also have less distance to cover.
Inertia is the resistance of objects tendency to move. So if you are playing a sport on a rough terrain with an object. The object will not move in a straight line or roll as fast or bounce as high.
this object that appears to stay in place is a reference point.
Velocity is negative in a moving object when the object is moving in the opposite direction of its positive reference point.
the force or other moving object
it means an object is moving based on the force of friction and gravity.
Kinetic energy
The friction of a non-moving object is called static friction. It is the force that prevents the object from moving when a force is applied to it.
it may tell the speed of the moving object
moving
The frequency of a sound wave created by a moving object will increase if the object is moving towards the observer and decrease if the object is moving away. This effect is known as the Doppler effect.
