Momentum and Impulse (PowerPoint)
... In an explosion internal forces are responsible for the object breaking apart. Because the pieces impart equal and opposite forces on each other (Newton’s third law) these internal forces cannot provide a net change in momentum so momentum must be conserved in explosions ...

... • The objective for the current chapter is to investigate the effects of forces on particles: - replacing multiple forces acting on a particle with a single equivalent or resultant force, - relations between forces acting on a particle that is in a state of equilibrium. • The focus on particles does ...

... 10. Which one of the following statements best explains why an astronaut experiences "weightlessness" in an orbit 1237 km above the earth? A) The centripetal force of the earth on the astronaut in orbit is zero newtons. B) The pull of the earth on the spaceship is canceled by the pull of the other p ...

... The force which opposes the movement or the tendency of movement is called Frictional force or simply friction. It is due to the resistance to motion offered by minutely projecting particles at the contact surfaces. However, there is a limit beyond which the magnitude of this force cannot increase. ...
