Momentum and Its Conservation
... Impulse and Momentum Using the Impulse-Momentum Theorem Let’s discuss the change in momentum of a baseball. The impulse that is the area under the curve is approximately 13.1 N·s. The direction of the impulse is in the direction of the force. Therefore, the change in momentum of the ball also is 13. ...

... Answer: D Justification: We can narrow down the answer by looking at what forces are acting on the stone after it is thrown up in the air. Since the only force acting on the stone is the force of gravity, we know that the stone must have a constant downward acceleration of 9.8 m/s2 (this acceleratio ...

... We orient our coordinate axes parallel and perpendicular to the ramp, and we replace the weight force by its components. Solve The car is in equilibrium, so we first find the components of each force in our axis system and then apply Newton’s first law. To find the components of the weight, we note ...

... The correct answers are (b) and (d). To understand the motion described by an x – t graph, consider the behavior of the velocity as found from the slope of the x – t plot. In Figure 2.18, this slope—and therefore the velocity—are largest at early times and fall to zero at the end of the motion. Henc ...

7. Friction - Sakshieducation.com
... When a body is in motion over another surface or when an object moves through a viscous medium like air or water or when a body rolls over another, there is a resistance to the motion because of the interaction of the object with its surroundings. Such a resistance force is called force of friction. ...
