What law of motion is it when you feel a force against the sole of your foot as you take a step forward?
Newton's 3rd law of motion states is basic terms that for every action there is an equal, but opposite reaction (if you push against a wall with force F, then the wall will push back with force -F). When you walk/run forward, you exert a force on the ground that goes diagonally down and backward. The equal, but opposite reaction is the ground exerting a force on your foot that is diagonally up and forward (exactly opposite that applied by your foot). This helps to propel you forward as you walk or run.

The tendency of an object to stay at rest or in constant motion unless a force acts upon it?
It's the mass of the object! An object with large mass are more viscous to set in motion. This effect, the viscousity of materia in universe may feel logical. But it's actually a mysterious phenomenon that we yet can't really describe!
What is inertia and orbital motion?
The natural tendency of an object to not move (if it wasn't moving), or to keep moving (if it was moving). Inertia is the characteristic that a object will want to stay at rest or in motion. You can feel this in a buss when it suddenly moves this is why you get sent backwards.
How is newtons law of motion used in amusement park rides?
An amusement park ride relates to Newton's First Law of motion because an object in motion will stay in motion and an object at rest will stay at rest unless acted apon by an unbalanced force. A Rolller Coaster for example, at first it stays at rest until the engine moves it (the unbalanced force). After it is moving it stays in motion unless acted upon by an unbalanced force (the brakes).
What is a force only exerted when objects touch?
A contact force? The answer really depends on the level of the question. Primary school answer: A pushing or pulling force, or a friction force occur when objects touch. High school answer: Same as above, but 'pushing' and 'pulling' would be replaced with positive and negative. Friction would be defined as a force that opposes motion, and would include air resistance and drag. University answer: Technically, there is no such force, as all forces act at a distance without touching. In fact, objects don't actually 'touch' one another at all. The outer electrons in an object's atoms will repel said electrons from another object's atoms through the electromagnetic force. This only makes it feel like the objects have come into contact with one another, when in fact they haven't.
According to newton's law of universal gravitation you are attracted to all objects around you Why can you not feel the forces between you and the objects around you?
You must be too far from the Earth to feel the force between you and the Earth. Right now I'm ~6400 km from the center of the Earth; you must be much farther away.A2 You can't feel the gravitational force that a mountain or a building attracts you because the force is too small. The force is proportional to your mass times the other mass and only the earth has a large enough mass for this force to be felt, which is your weight. Gravity is considered the weakest of the fundamental forces.
What is air resestance?
When you run forward fast tou will feel the air rushing past you. The faster you go the more you will feel the air. This is because to move forward you have to push the air ahead of you out of the way, the energy required to do this is called air resistance or drag. Simply put, a doubling of the speed of something moving though the air, quadruples the air resistance (the drag force) acting against its forward motion.
Is force necessary in motion?
Yes force is necessary to cause motion. If an object is at rest the net forces acting on it are zero so it will remain in that state. The same goes for a body which is in motion, so long as the velocity remains constant with time you will not feel an accelerating force. The force that you feel will come into play when you wish increase or decrease your velocity. In order to do this you must accelerate, which in turn generates the force that you feel. The momentum of a body is the product of its mass times its velocity. Force is equal to the mass of the body multiplied by the time rate of change of its velocity.
Example pushing on a wall?
When you push on a wall, the wall exerts an equal and opposite force back on you, as described by Newton's third law of motion. This is due to the interaction between the force you apply to the wall and the reaction force the wall applies to you. As a result, you may feel the resistance of the wall pushing back against you.
When you ride a bus why do you fall forward when the bus stops moving?
This happens because of the force inertia, which is "the property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not acted upon by an external force" according to dictionary.com. This means that if something is moving it will keep its velocity or movement the same and keep going even if the thing it is in stops, like a car slamming on its brakes and the passengers jerking forward.
What force makes us move forward when a car suddenly stops?
This is not a force, but your conservation of momentum. For there to be a force, you must have some acceleration, but what you feel is actually your body attempting to continue moving forward until the force of friction and force normal of your seat belt decelerate you.
Can air resistance be felt on the ground?
Of course. Next time you're riding in a car, stick your hand out of the window, with your palm facing forward. Can you feel the force ? That's air resistance.
What do you feel when you hold and object against the pull of gravity?
When you hold an object against the pull of gravity, you feel a sensation of weight in your hand due to the force required to counteract gravity. This feeling can vary depending on the mass of the object and the strength of the gravitational force acting on it.
Is there gravity in a rocket ship?
If the rockets are active then you will feel a gravitational force pulling you down in the direction opposite the rocket's motion. If they are off however you are weightless and you experience no gravitational force.
What force acts against gravity in water?
Buoyant force acts against gravity in water. This force is exerted by the water on an object that is submerged or floating in it and acts in the opposite direction to gravity. Bouyant force is what allows objects to float and feel lighter when in water.
What is the reason you feel a pulse?
This is the force of the blood being pumped in an artery pressing against the arterial walls.
What happens when the gravitational force acting on an object is changed?
When the gravitational force acting on an object changes, the object's weight may change accordingly. If the force increases, the object will feel heavier, and if the force decreases, the object will feel lighter. This change in gravitational force can also impact the object's motion and trajectory if it is in free fall or orbit.
Does gravity decrease or increase driving uphill?
Gravity remains constant regardless of the direction you are driving in. However, the gravitational force may feel stronger when driving uphill due to the incline causing a greater component of gravity to act against the vehicle's motion.
