PHYSICS 231 Review problems for midterm 1 1 PHY 231
... The reading of the scale equals the normal force provided by the scale. Write down Newton’s law for the forces acting on you: F=ma n-mg=ma (normal force n is pointing up, gravitational force is pointing down) The elevator is accelerating upwards, so a>0 and thus: n>mg which means that the weight y ...

... By Newton's 3rd Law, the particles pull on each other with equal and opposite forces. By Newton's 2nd Law, for the same force the particle with less mass undergoes more acceleration. By Coulomb's Law, as the separation distance is decreased, the force increases. By Newton's 2nd Law, as the force inc ...

... The perpendicular component of force still balances the normal force since objects do not accelerate perpendicular to the incline. The perpendicular component and the normal force add to 0 N. Yet the frictional force must also be considered when determining the net force. The parallel component and ...

... The best method of getting a spacecraft from the Earth to Mars would be to launch it A. to the east, then in the same direction as the Earth's orbit B. to the west, then in the opposite direction to the Earth's orbit C. directly at Mars with sufficient velocity to escape the Earth's gravitational fi ...

... 1. Look to see if an object can be considered as a combination of simpler objects: a sledge hammer can be considered as a solid cylinder (the handle) with a second cylinder (the head) mounted perpendicular to the first. 2. Look for symmetry. If there is a plane of symmetry, the center of mass must b ...
