... 7. If we know an object is moving at constant velocity, we may assume: a. there are no forces acting on the object. b. the net force acting on the object is zero. c. the object is accelerating. d. the object is losing mass. 8. A 7.0-kg bowling ball experiences a net force of 5.0 N. What will be its ...

... Weight vs. Mass Mass is the amount of matter. It is a measure of inertia. Weight of an object is a result of the Earth’s attraction downward. Weight is a downward force. Example: An astronaut in space has the same mass as he does on earth while having different weights. This is because there is a di ...

... Answer. Kepler was not aware of the law of inertia, or at least didn't apply it to this situation. The cannonball at rest in the cannon has the same speed as the earth's surface at that point. Its firing speed is relative to the moving earth, so there would be practically no difference in range whet ...

Work and the Work-Energy Principle
... • Work is what is accomplished by a force acting on an object (i.e., movement in the direction of that particular force) • Work is a scalar quantity - no direction • It can, however, be either positive or negative. Positive if the object moves at least partly in the direction of the force. Negative ...
