Why is centrifugal force a fictitious force and centripetal force a real force?
Centrifugal force is considered a fictitious force because it only appears to act on objects in a rotating reference frame, such as a spinning carousel or a turning car. In reality, the object is moving in a straight line, but it appears to be pushed away from the center of rotation due to inertia. On the other hand, centripetal force is a real force that acts towards the center of rotation, keeping an object moving in a circular path. This force is necessary to maintain the object's curved motion and prevent it from moving in a straight line.

Which force?
The force of gravity is the fundamental force that governs the motion of objects in the universe. It is responsible for keeping planets in orbit around the sun, causing objects to fall to the ground, and creating tides on Earth. Gravity is a universal force that acts between all objects with mass, and its strength depends on the mass of the objects and the distance between them.

Which force is responsible for the centripetal force?
The centripetal force is responsible for keeping an object moving in a circular path. This force is provided by another force acting towards the center of the circle, such as tension in a string, gravitational force, or friction. Without this centripetal force, the object would move in a straight line tangent to the circle.

Which of these forces has nothing to do with physical forces: lifting force, frictional force, tension force, thrust force? Why?
Tension force has nothing to do with physical forces. Tension force is a force that is transmitted through a string, rope, cable, or wire when it is pulled tight by forces acting from opposite ends. It is a result of the electromagnetic forces between the atoms and molecules in the material. Therefore, tension force is not a physical force like lifting force, frictional force, or thrust force, which are related to the interaction of objects in the physical world.

What is the difference between the force of gravity, the force of acceleration, the weight force, the gravitational force, and the force of gravity by definition?
The force of gravity is the force of attraction between two objects due to their mass. The force of acceleration is the force that causes an object to change its speed or direction. Weight force is the force exerted on an object due to gravity, and it is equal to the mass of the object multiplied by the acceleration due to gravity. Gravitational force is the force of attraction between two objects with mass, and it is proportional to the product of their masses and inversely proportional to the square of the distance between them. The force of gravity by definition is the force of attraction between two objects with mass, and it is responsible for the phenomenon of gravity.

Is the frictional force proportional to the normal force?
Yes, the frictional force is proportional to the normal force. This relationship is described by the equation F_friction = μ * F_normal, where μ is the coefficient of friction. The coefficient of friction represents the ratio of the frictional force to the normal force, and it remains constant as long as the surfaces in contact and the conditions remain the same. Therefore, an increase in the normal force will result in a proportional increase in the frictional force.

How do you add weight force and centripetal force?
To add weight force and centripetal force, you need to consider the individual forces acting on an object. Weight force is the force acting downwards due to gravity, while centripetal force is the force required to keep an object moving in a circular path. To add these forces, you would calculate the weight force using the formula F = m * g, where m is the mass of the object and g is the acceleration due to gravity. For centripetal force, you would use the formula F = m * v^2 / r, where m is the mass of the object, v is the velocity, and r is the radius of the circular path. By calculating and adding these forces, you can determine the total force acting on the object.

How do you calculate weight force and tension force?
Weight force is calculated by multiplying an object's mass by the acceleration due to gravity (9.8 m/s^2). The formula for weight force is: weight force = mass x acceleration due to gravity. Tension force in a rope or string is calculated by considering the forces acting on the object at the ends of the rope. The tension force is equal in magnitude and opposite in direction at each end of the rope, and is calculated using Newton's second law: tension force = mass x acceleration.

'Love or force?'
Love is always the better choice. Force may achieve shortterm compliance, but it does not build trust or genuine connection. Love, on the other hand, fosters understanding, empathy, and mutual respect. It allows for open communication and the willingness to compromise, leading to stronger and more fulfilling relationships.

What is the difference between gravitational force and attractive force?
Gravitational force is a specific type of attractive force that exists between any two objects with mass, as described by Newton's law of universal gravitation. On the other hand, attractive force is a more general term that can refer to any force that pulls objects together, such as electromagnetic forces or nuclear forces. While gravitational force specifically involves the mass of objects, attractive forces can be due to a variety of factors depending on the context.

What is the difference between total force and restoring force?
Total force is the sum of all forces acting on an object, including external forces like gravity, friction, and applied forces. Restoring force, on the other hand, is a specific type of force that acts to bring an object back to its equilibrium position after it has been displaced. Restoring force is often associated with systems like springs or pendulums, where the force is proportional to the displacement from equilibrium.
