Newton's Third Law: the force between two objects and reaction are always equal and opposite, and the role of a straight line. F1 =- F2① force's role is mutual. Also appear at the same time disappear.② interaction force must be of the same nature③ reaction force and the role of ...
Force, in mechanics, any action that tends to maintain or alter the motion of a body or to distort it. The concept of force is commonly explained in terms of Isaac Newton’s three laws of motion. Because force has both magnitude and direction, it is a ve
Magnetic force can be seen between the poles of 2 magnets. It is either attractive or repulsive depending upon the orientation of the object. It can be said to be a consequence of Electrostatic forces.FAQs What is force and its unit? Force is a physical cause that changes or may tend to...
force is applied to it. Thesecond lawsays that when an external force acts on a body, it produces anacceleration(change in velocity) of the body in the direction of the force. The magnitude of the acceleration is directly proportional to the magnitude of the external force and inversely ...
How much force is a newton? How does force, time, displacement, and velocity affect power? How do you find the magnitude of average acceleration? How is force expressed in terms of momentum? How does gravitational force work? What is the difference between constant velocity and acceler...
2. Find the approximate distance between the earth and the planet Mars given the force between the two planets is 10^(16) Newtons (N). Also, the mass of the earth can be used from question 1 above, while the mass of Mars is 6.4 x 10^(23) kg. Answers 1. From the question we...
If a box is sliding to the right, what direction is the force of friction on the box? 4. Name one difference between mass and weight. 答案 1.p=m*v,where p is the momentum,m is the mass,and v is the velocity.The momentum is a vector.2.Newton's Third Law:For every action,...
The resultant force is the net force acting on an object. If two people are pulling on a rope in opposite directions, the resultant force is the difference between the two. What is the formula for the resultant force vector? The formula for the resultant force vector is given by Newton's...
These are some important effects of force. Types of Forces Contact Force Any force which requires interaction with the surface is referred to as a contact force. Contact forces are everywhere and are responsible for nearly every visible contact between macroscopic matter. Muscular Force Muscular ...
