A body whose momentum is constant

All of these. A body falls freely. What is constant?

This action cannot be undone. This will permanently delete All Practiced Questions. A force of 50 dynes is acted on a body of mass 5 g which is at rest for an interval of 3 seconds, then impulse is. These forces are represented in magnitude and direction by the three sides of a triangle ABC as shown. The particle will now move with velocity.

So far, we have looked at the angular momentum of systems consisting of point particles and rigid bodies. We have also analyzed the torques involved, using the expression that relates the external net torque to the change in angular momentum. In this case, we can introduce the law of conservation of angular momentum. The angular momentum of a system of particles around a point in a fixed inertial reference frame is conserved if there is no net external torque around that point:. Any of the individual angular momenta can change as long as their sum remains constant. This law is analogous to linear momentum being conserved when the external force on a system is zero.

A body whose momentum is constant

The learning objectives in this section will help your students master the following standards:. Using the example of football players, point out that both the mass and the velocity of an object are important considerations in determining the impact of collisions. The direction as well as the magnitude of velocity is very important. In equation form, linear momentum p is. A large, fast-moving object has greater momentum than a smaller, slower object. Momentum is a vector and has the same direction as velocity v. Since mass is a scalar , when velocity is in a negative direction i.

A body of mass M at rest explodes into three pieces, two of which of m If all the forces acting on the body are coplanar, then we need only three conditions to be satisfied for mechanical equilibrium. Find the magnitude of the third force.
