Any object moving along a line has a veryimportant property. This property is called the linearmomentum. The combination of the mass and velocityof the object. Quantitatively we have the linearmomentum of a moving object as the product of themass (m) and velocity (v).P = mvNote;Linear momentum is a vector (with magnitudeand direction).

Relativistic Energy and Momentum

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience this effect in everyday life. This effect is only observed when an object moves with some velocity comparable to the velocity of light. This velocity is termed relativistic velocity.

Question

Any object moving along a line has a very
important property. This property is called the linear
momentum. The combination of the mass and velocity
of the object. Quantitatively we have the linear
momentum of a moving object as the product of the
mass (m) and velocity (v).
P = mv
Note;
Linear momentum is a vector (with magnitude
and direction). It takes the same direction as that of
the moving object.
Exercises;
Compare the momentum of a car with mass
1800 kg moving at a velocity of 90km/hr and a
velocity of 120 km/hr. at which momentum is
greatest/ How does velocity affects the
momentum of a moving object at constant
mass?

Learning Goal: To understand the relationship between force, impulse, and momentum. The effect of a net force EF acting on an object is related both to the force and to the total time the force acts on the object. The physical quantity impulse J is a measure of both these effects. For a constant net force, the impulse is given by J = FAt. The impulse is a vector pointing in the same direction as the force vector. The units of J are N. sor kg · m/s. Recall that when a net force acts on an object, the object will accelerate, causing a change in its velocity. Hence the chiect's momentum in- mail will also change.
