"In classical mechanics, impulse (symbolized by J or Imp) is the change in momentum of an object."
Impulse and momentum are concepts used to describe the physical world in terms of the forces applied, the amount of time over which they are applied, and the mass of the object upon which they are acting.
Conservation of Momentum: This is a foundational concept in dynamics that states that the total momentum of a system is conserved in the absence of external forces.
Impulse: Impulse is the change in momentum of an object when an external force acts on it for a specific amount of time.
Newton's Laws of Motion: These are three fundamental laws that explain the relationship between forces and motion.
Kinematics: Kinematics is the study of motion without considering its cause or forces that affect it.
Elastic and Inelastic Collisions: These refer to types of collisions between objects where there is either a complete transfer of energy or not.
Force: Force is a push or pull on an object and is directly related to changes in momentum.
Friction: Friction is a force that opposes the motion of an object and affects its momentum.
Impulse-Momentum Theorem: This theorem states that the change in momentum of an object is equal to the impulse of the external force acting on it.
Conservation of Energy: This principle states that energy cannot be created or destroyed but can be transferred or transformed.
Center of Mass: This is the point where the total mass of a system is located and is used to analyze the motion of the system.
Work-Energy Theorem: This theorem states that the net work done on an object is equal to its change in kinetic energy.
Torque: Torque is a force that causes rotation and affects the angular momentum of an object.
Angular Momentum: Angular momentum is the product of an object’s moment of inertia and its angular velocity and is conserved in the absence of external torques.
Rotational Kinematics: This is the study of motion of objects that rotate around an axis.
Moment of Inertia: This is the resistance of an object to changes in its rotational motion and depends on the object’s mass distribution.
Projectile Motion: Projectile motion is the motion of an object that is launched into the air and follows a parabolic path.
Rigid Body Dynamics: This is the study of the motion of objects that don’t deform as they move and are governed by torque, angular momentum, and moment of inertia.
Linear Momentum: This is the product of an object’s mass and velocity and is a conserved quantity in the absence of external forces.
Angular Velocity: This is the rate of change of an object’s angular position and is used to describe the motion of rotating objects.
Inertia: Inertia is the tendency of an object to resist changes in its motion and is directly related to its mass.
Linear Momentum: The product of an object's mass and its velocity in a straight line.
Angular Momentum: The product of an object's moment of inertia and its angular velocity.
Impulse: The change in momentum of an object caused by a force acting on it for a period of time.
Conservation of Momentum: The principle that the total momentum of a closed system remains constant if no external forces act on it.
Elastic Collision: A collision in which the total kinetic energy and momentum of a system is conserved.
Inelastic Collision: A collision in which some of the kinetic energy is lost as heat or sound, resulting in a decrease in the total momentum of the system.
Perfectly Inelastic Collision: A special case of inelastic collision where the objects stick together after the collision.
Impulsive Force: A force that acts on an object for a very short period of time, resulting in a large change in momentum.
Recoil: The backward movement of a firearm after firing a bullet, caused by the object's conservation of momentum.
Rocket Propulsion: The propulsion system used in rockets, which works based on the principle of conservation of momentum.
"Momentum is a vector quantity, so impulse is also a vector quantity."
"Newton’s second law of motion states that the rate of change of momentum of an object is equal to the resultant force F acting on the object."
"The impulse J delivered by a steady force F acting for time Δt is: J = FΔt."
"The impulse delivered by a varying force is the integral of the force F with respect to time."
"The SI unit of impulse is the newton second (N⋅s)."
"The dimensionally equivalent unit of momentum is the kilogram metre per second (kg⋅m/s)."
"The corresponding English engineering unit is the pound-second (lbf⋅s)."
"In the British Gravitational System, the unit is the slug-foot per second (slug⋅ft/s)."
"Impulse (symbolized by J or Imp) is the change in momentum of an object."
"Impulse is also a vector quantity."
"If the initial momentum of an object is p1, and a subsequent momentum is p2, the object has received an impulse J."
"The magnitude of impulse is determined by the force acting on the object and the duration of that force."
"The impulse J delivered by a steady force F acting for time Δt is: J = FΔt."
"The impulse delivered by a varying force is the integral of the force F with respect to time."
"Impulse is the change in momentum of an object."
"Impulse is measured in the newton second (N⋅s)."
"Momentum is measured in the kilogram metre per second (kg⋅m/s)."
"The equivalent unit of impulse in the English engineering system is the pound-second (lbf⋅s)."
"The unit of impulse in the British Gravitational System is the slug-foot per second (slug⋅ft/s)."
