Explain the concept of action-reaction pair in the context of forces.
According to Newton's third law of motion, for every action, there is an equal and opposite reaction. In the context of forces, this means that whenever an object exerts a force on another object (action), the second object exerts an equal and opposite force on the first object (reaction). Action-reRead more
According to Newton’s third law of motion, for every action, there is an equal and opposite reaction. In the context of forces, this means that whenever an object exerts a force on another object (action), the second object exerts an equal and opposite force on the first object (reaction). Action-reaction pairs are always present and act on different objects, ensuring that the forces are balanced and satisfy the law of conservation of linear momentum.
See lessDescribe the conservation of linear momentum in a rocket propulsion system.
In a rocket propulsion system, conservation of linear momentum is observed. As the rocket expels gas at high velocity in one direction (exhaust), an equal and opposite momentum is gained by the rocket in the opposite direction. This causes the rocket to move forward. By Newton's third law, the forceRead more

As the rocket expels gas at high velocity in one direction (exhaust), an equal and opposite momentum is gained by the rocket in the opposite direction. This causes the rocket to move forward. By Newton’s third law, the force exerted by the exhaust gas on the rocket is balanced by an equal and opposite force exerted by the rocket on the gas, ensuring conservation of momentum.
See lessExplain the concept of the center of mass.
The center of mass of a system is the point where the total mass of the system is considered to be concentrated. It is the average position of all the particles in the system, weighted by their respective masses. The center of mass is a useful concept in analyzing the motion of objects or systems, aRead more
The center of mass of a system is the point where the total mass of the system is considered to be concentrated. It is the average position of all the particles in the system, weighted by their respective masses. The center of mass is a useful concept in analyzing the motion of objects or systems, as the motion of the system can be simplified by considering it as a point mass located at the center of mass.
See lessDefine inelastic collision.
An inelastic collision is a collision between two or more objects where momentum is conserved but kinetic energy is not conserved. In an inelastic collision, the objects stick together or deform upon collision, resulting in a loss of kinetic energy. The total momentum of the system is still conserveRead more
An inelastic collision is a collision between two or more objects where momentum is conserved but kinetic energy is not conserved. In an inelastic collision, the objects stick together or deform upon collision, resulting in a loss of kinetic energy. The total momentum of the system is still conserved, meaning the vector sum of the momenta of the objects before the collision is equal to the vector sum of the momenta after the collision.
See lessDefine elastic collision.
An elastic collision is a collision between two or more objects where both momentum and kinetic energy are conserved. In an elastic collision, the total kinetic energy before and after the collision remains the same. Additionally, the total momentum of the system is conserved, meaning the vector sumRead more

See lessDefine the term “momentum.”
Momentum is defined as the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction. The momentum of an object determines the amount of force required to change its state of motion.

See lessExplain why the momentum of the gun changes during the firing of a bullet.
The momentum of the gun changes during the firing of a bullet due to the principle of conservation of linear momentum. As the bullet is propelled forward with a certain momentum, an equal and opposite momentum is imparted to the gun in the backward direction, causing its momentum to change.
