Newtons Laws of Motion

Any pair of forces that has the same magnitude (strength) and opposite direction.

For example, when putting an object on atablet (a puppy)

Gravity acts upon the puppy to pull it down but it doesn't go down because there is a force that the table is acting on the puppy, with the same magnitude as the gravity but the direction is upward.

=> equilibrium forces.

According to the "Mythbuster's Bug Special", about 23,000 bees would be required to lift up a laptop.

An action-reaction pair is a pair of objects that interact to produce a force on each other of equal magnitude but of opposite direction. Object A exerts a force on object B that pushes/pulls it; and object B exerts a force on object A that pulls/pushes it (respectively).

It is a concept based on Newton's third law of physics.

For ex. The earth has a gravitational force on the moon (which in part keeps the moon in orbit) but the moon also has a force on the earth (which causes the welling up of water- i.e. the tides- during different phases of the moon).

Travelers in a ring frame in textile spinning are small, metal components that guide the yarn around the spinning ring. The traveler moves along the ring rail in a circular motion, driven by the rotation of the ring and the yarn passing through it. This movement helps to ensure proper tension and even distribution of the yarn as it is spun into a thread.

No work is taking place and no energy is moving outside of your body.

The movement of energy is all in your muscles, and it gets dissipated

as the sweat trickles out of your skin and evaporates into the air.

The first law can be derived from the second law but I don't think the second law can be derived from the third law.

Newton's second law states that the rate of change of momentum is proportional to the resultant force and acts in the same direction as the resultant force.

For a constant mass, F = ma

This means that if F (the resultant force) is zero, a (acceleration) is zero. Thus, if the resultant force on a body is zero, a body continues in its state of rest or uniform motion in a straight line. This is Newton's first law.

The object will remain at rest if it was at rest or will maintain its motion with uniform velocity if it was moving.

Yes, jumping on a trampoline is an example of Newton's third law of motion. As you push down on the trampoline, it pushes back with an equal force, propelling you upward. This action-reaction pair demonstrates Newton's third law that states for every action, there is an equal and opposite reaction.

This is explained by Newton's First Law of Motion, which states that an object in motion tends to stay in motion unless acted upon by an external force. As the car turns a corner quickly, your body continues to move in a straight line due to inertia, causing you to lean sideways relative to the car's movement.

According to Newton's First Law of Motion, the marble will remain at rest unless acted upon by an external force. In this case, if no external force is applied to the marble, it will continue to stay still in the middle of the floor.

Pascal is the s.i unit of upthrust

If the forces act in same direction then by vector addition answer should be 49N . But answer will be different if forces are in different directions .

Let's be very accurate when describing accelerations in this question.

Consider a person at the equator. The gravitational force of attraction on him is constant whether or not the earth is rotating. This acceleration is called the acceleration due to gravity (ag)

Now, since the earth is rotating about its axis, there has to be a centripetal force on the person. It is the gravitational force which provides the centripetal force. Thus, there is a centripetal acceleration on the person (ac)

Finally, the rest of the gravitational force causes the person to accelerate towards earth. This is called the acceleration of free fall (af)

This gives ag = ac + af

ac is given by the equation: ac = w2r

where w is the angular velocity and r is the radius of rotation

If the angular velocity of the earth increases, centripetal acceleration will increase.

af = ag - w2r

Therefore, the acceleration of free fall will decrease.

Mass doesn't like to move. Rather, it doesn't like to be forced to move. The first law of motion by Newton states that an object in motion will stay in motion until an external force is acted upon it. The second law of motion by Newton states that force is equal to mass multiplied by acceleration. The more something weighs, or the more mass it has, the more acceleration or force is required to move it.

So to answer your question shortly, increase in mass affects how much acceleration or force is needed to move that mass.

It typically takes about 110-130 Newtons of force to knock over a standard 15-inch-tall bowling pin. This force can vary depending on factors such as the weight of the bowling ball and the angle at which it strikes the pin.

If forces are balanced, the acceleration of the object will be zero and the velocity will be constant. Maybe zero maybe not.

Since the Earth is rotating, and moving through space, and the rock is moving along with the Earth, then it does, but relative to the Earth, I'd say that the momentum of the rock (mass * velocity) is essentially zero.

Newton's first law states that an object in motion will remain in motion unless acted upon by an external force. In the case of an object moving in a circular path, centripetal force is required to keep the object moving in that path, not centrifugal force. Centrifugal force is a perceived force that arises from the object's inertia, rather than a true force acting on the object itself.

Newton's first equation 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 other words, an object will maintain its velocity unless a net external force is applied to change it.

When forces are balanced, the object at rest will remain at rest, while the object in motion will continue to move at a constant velocity. This is due to Newton's first law of motion, which states that an object will remain at rest or in motion with constant velocity unless acted on by an unbalanced external force.

The force needed to slide the mass at a constant velocity is equal in magnitude and opposite in direction to the frictional force. The frictional force is calculated as the coefficient of friction multiplied by the normal force (frictional force = coefficient of friction * normal force). Hence, the force needed would be 0.43 times the weight of the mass (force = coefficient of friction * mass * gravity).
