Common questions about momentum calculations
Momentum is a measure of an object's motion, calculated as the product of its mass and velocity. It's a vector quantity that describes how difficult it is to stop a moving object.
Linear momentum is calculated using the formula p = mv, where p is momentum, m is mass, and v is velocity. The units are kg·m/s.
Momentum (p = mv) is a vector quantity that depends on mass and velocity, while kinetic energy (KE = ½mv²) is a scalar quantity that depends on mass and the square of velocity.
Impulse is the change in momentum of an object when a force is applied over time. It's calculated as J = FΔt, where F is force and Δt is the time interval.
Conservation of momentum states that in a closed system with no external forces, the total momentum before a collision equals the total momentum after the collision.
To find momentum from kinetic energy, first solve for velocity: v = √(2KE/m), then calculate momentum: p = mv. This works when you know the mass and kinetic energy.
In elastic collisions, both momentum and kinetic energy are conserved. In inelastic collisions, momentum is conserved but kinetic energy is not (some energy is lost as heat or deformation).
To analyze collisions, use conservation of momentum (p₁ + p₂ = p₁\' + p₂\') and determine if it's elastic or inelastic. For elastic collisions, kinetic energy is also conserved.
Force is the rate of change of momentum: F = Δp/Δt. This means that applying a force over time changes the object's momentum. The impulse-momentum theorem states J = Δp.
Momentum is typically in kg·m/s, but you can convert between units. For example, 1 kg·m/s = 1000 g·cm/s. Always ensure mass is in kg and velocity is in m/s for standard calculations.
