Three fundamental laws that describe the relationship between forces and motion. They are used to predict the motion of objects and are essential in understanding dynamics.
Force and Motion: This topic deals with the fundamental concept of force and motion, including their definitions and the relationship between them.
Inertia: Inertia is the property of an object that resists any change in its state of motion. It is one of the foundations of Newton's laws.
Newton's First Law of Motion: This law states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.
Mass: Mass is a measure of an object's resistance to acceleration. It is a key concept in understanding Newton's laws.
Newton's Second Law of Motion: This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
Friction: Friction is the force that opposes motion between two surfaces that are in contact with each other. It is a common force in everyday life.
Newton's Third Law of Motion: This law states that for every action, there is an equal and opposite reaction.
Momentum: Momentum is a measure of an object's motion and is calculated by multiplying its mass and velocity.
Impulse: Impulse is the change in momentum of an object due to a force acting on it for a certain amount of time.
Conservation of Momentum: This principle states that the total momentum of a closed system is conserved in the absence of external forces.
Elastic and Inelastic Collisions: Collisions can either be elastic or inelastic, depending on the conservation of momentum and kinetic energy.
Gravity: Gravity is the force by which a planet or other body draws objects towards it. It is another force that plays an important role in understanding dynamics.
Projectile Motion: Projectile motion is the motion of an object under the influence of gravity and air resistance.
Circular Motion: This topic deals with the motion of an object moving in a circular path, including the centripetal force and the relationship between force and velocity in circular motion.
Work and Energy: Work is the transfer of energy from one object to another due to the application of a force. Energy is the ability to do work, and the two are related by the work-energy principle.
Power: Power is the rate at which work is done, or the rate at which energy is transferred.
Torque: Torque is the tendency of a force to cause rotation, and is calculated as the product of force and the moment arm.
Laws of Thermodynamics: The laws of thermodynamics deal with the relationship between energy and its transformation, which is relevant in understanding how energy is transferred in various systems.
Newton's First Law of Motion: This is also known as the law of inertia. It states that an object will remain in a state of rest or continue to move at a constant velocity in a straight line, unless acted upon by an external force.
Newton's Second Law of Motion: This law describes how a force affects the motion of an object. It states that the acceleration of an object is directly proportional to the force applied to it, and inversely proportional to its mass. This can be mathematically represented as F=ma, where F is the force, m is the mass of the object, and a is the acceleration produced.
Newton's Third Law of Motion: This law states that for every action, there is an equal and opposite reaction. When one object exerts a force on another object, the second object exerts an equal and opposite force on the first. This pair of forces is sometimes referred to as an "action-reaction pair".
