Is the push on your back a resistance to motion when your body is at rest in a moving bus if Newton's Law says every body continues in its state of rest or uniform motion unless otherwise acted upon?

The effect of being "pushed" back in the bus is in fact not a force applied on the passengers. The feeling of being pushed back is actually the passengers' inertia (or propensity to remain at the same velocity) continuing to remain at the same velocity as before, at rest. Thus, the bus is literally moving under your feet when your body remains at the same velocity as before; thus, the force applied in this situation is actually in the same direction as the acceleration of the bus since your body needs to move with the bus rather than fly towards the back of the bus. Inertia, is resistance to change: A mass at rest resists being put into motion; The momentum of a moving mass, resists all forms of change in its straight line motion. Inertia, is resistance; momentum is force.

Yes, the push on your back is a resistance to motion when your body is at rest in a moving bus because Newton's First Law states that an object at rest will stay at rest unless acted upon by an external force. In this case, the push from the bus seat is the external force acting on your body.

What are prescribable uniform items?
Prescribable uniform items are items such as clothing or equipment that are required for a specific profession and are prescribed by an authority, such as a regulatory body or employer. These items ensure consistency and professionalism in appearance among individuals within the profession.
What occurs when there is no air resistance?
-- "free fall" -- absence of terminal velocity
What are the causes of uniform projectile?
Uniform projectile motion is caused by the combination of an initial velocity and the force of gravity acting on the object. As long as there are no other external forces acting on the object, such as air resistance or friction, the object will follow a predictable parabolic path.
How does newtons law and inertia in space?
Newton's first law of motion states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. In space, where there is very little friction or air resistance, objects will continue moving in a straight line at a constant velocity once set in motion, exhibiting inertia. This is why spacecraft can maintain their trajectory once launched and do not require constant propulsion to keep moving.
Why the motion of sphere becomes uniform after a certain time?
The motion of a sphere becomes uniform after a certain time due to the balance between external forces (if any) and internal forces like friction or air resistance that act upon the sphere. Once the sphere reaches a steady state, the external and internal forces cancel each other out, resulting in a uniform motion.

Does the Law of Inertia state that a body remains at rest or continues in a state of uniform motion unless a force act on it?
The Law of Inertia states that a body continues in a state of uniform motion unless a force act on it.
What are prescribable uniform items?
Prescribable uniform items are items such as clothing or equipment that are required for a specific profession and are prescribed by an authority, such as a regulatory body or employer. These items ensure consistency and professionalism in appearance among individuals within the profession.
What is 1st law of motion?
Newtons 1st law states that every body continues to be in its own state of rest or of uniform motion along a straight path unless it is compelled by any external force to change its state. If a force is exerted on a body the body will move but without force it will not move.
How acceleration occur in a straight pattern?
It just does, in the absence of other forces ( ie air and rolling resistance ), that is to say under ideal conditions, a constant force on a fixed mass will produce uniform acceleration (velocity change) acceleration ( (m/s)/s ) = force (newtons) / mass (kg)
What is inrtia?
Inertia is the tendency of an object to resist changes in its state of motion. This means an object at rest will remain at rest, and an object in motion will continue moving at a constant velocity unless acted upon by an external force. The greater the mass of an object, the greater its inertia.
What is the definition of prescribable items?
Uniform items which may be directed or authorized for wear with the basic uniform. Items may be worn with basic uniform at the individual's discretion unless otherwise directed
When a pearl is dropped into a dense liquid it quickly acquires a uniform non accelerated motion downward why does this happen?
It accelerates quickly up to a low terminal velocity, then continues at constant velocity. At terminal speed, the downward force of gravity and the upward force of liquid resistance are in balance.
What is the definition newtons laws of motion?
Newton's First law of motion states that everybody continues or tends to be in its state of rest, or of uniform motion, unless it is compelled to change that state by force impressed on it.
What happens when you apply force in an object in space?
It accelerates as long as the force is applied, and after that it continues at a uniform speed and direction.
The pioneer 10 spacecraft has left your Solar System and is traveling at a speed of 29000 mph and has been doing so for years Explain why this object is moving so fast although it ran out of fuel?
it is because according to newtons law A body continues to maintain its state of rest or of uniform motion unless acted upon by an external unbalanced force.so once the initial speed was acquired it kept going on with that speed
