Weba 145 gram baseball. a 540 gram croquet ball. an 8200 gram bowling ball. Question 4. 120 seconds. Q. Two separate cannons with the same explosive charge fire different sized cannon balls. One cannon ball weighs 2 kg, and the other weighs 4 kg. The lighter 2-kg balls travels twice as fast from the cannon as the heavier 4-kg ball. WebFrictional force is defined as frictional coefficient x normal force. In this instance normal force is equal and opposite to Gravitational force which is equal to mass x gravity constant. So if you substitute all of this in you are left with two equations, assuming frictional force …
What is Force? - Definition, Unit, Types, Formula, Applications
WebFree-body diagrams are diagrams used to show the relative magnitude and direction of all forces acting upon an object in a given situation. A free-body diagram is a special example of the vector diagrams that were discussed in an earlier unit. These diagrams will be used throughout our study of physics. The size of the arrow in a free-body ... Web35 Questions Show answers Question 1 120 seconds Q. As the angle of the incline increases, what happens to the normal force? answer choices The normal force increases The normal force decreases The normal force is not affected by the incline The normal force is only dependent on the force due to gravity Question 2 60 seconds Q. convertizor kw in cp

The Standard Model explains how the basic building blocks of matter interact, governed by four fundamental forces. The theories and discoveries of thousands of physicists since the 1930s have resulted in a remarkable insight into the fundamental structure of matter: everything in the universe is found to be made from a few ... WebThe work we do on the rock also equals the rock’s gain in gravitational potential energy, PEe. W = P E e = m g d. Kinetic energy depends on the mass of an object and its velocity, v. K E = 1 2 m v 2. When we drop the rock the force of gravity causes the rock to fall, giving the rock kinetic energy. convert iu to mg conversion
