Q. Are acceleration and mass directly proportional?
Acceleration is produced by a net force on an object and is directly proportional to the magnitude of the force, in the same direction as the force, and is inversely proportional to the mass of the object.
Q. What relationship exists between mass and acceleration if force is constant?
Newton’s second law of motion states that acceleration is directly proportional to net force when mass is constant… and that acceleration is inversely proportional to mass when net force is constant…
Q. What is the relationship between force and acceleration quizlet?
What is the relationship between force and acceleration? Acceleration depends on how much force is acting on an object. How does motion change when the net force is zero? When the net force is zero there is no acceleration.
Q. What is the relationship between distance and force?
Increasing the separation distance between objects decreases the force of attraction or repulsion between the objects. And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects. Electrical forces are extremely sensitive to distance.
Q. Does force affect distance?
Distance refers to how far an object travels over a period of time. The greater the force that is applied on an object the further distance that object will travel.
Q. What is the relation between work done and force?
Force and work are directly proportional to each other, while force and displacement are indirectly propotional. The equation showing the relationship is W= Fd. W represents work measured in joules; F represents force in newtons; and d represents distance in meters.
Q. What is the force of distance?
Action-at-a-distance forces are those types of forces that result even when the two interacting objects are not in physical contact with each other, yet are able to exert a push or pull despite their physical separation. Examples of action-at-a-distance forces include gravitational forces.
Q. Is force directly proportional to distance?
Both forces are inversely proportional to the square of the distance between the objects, this is known as the inverse-square law. Also, both forces have proportionality constants. A difference between gravitational force and electric force is their relative strengths, related to the ratio of k to G.
Q. Which type of force is least sensitive to distance?
gravitational force
Q. Why does force decrease with distance?
Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.
Q. Is force proportional to position?
The force responsible for the motion is always directed toward the equilibrium position and is directly proportional to the distance from it. That is, F = −kx, where F is the force, x is the displacement, and k is a constant. This relation is called Hooke’s law.
Q. Why does force cause acceleration?
An unbalanced force acting on an object causes it to accelerate. The bigger the unbalanced force acting on the object the bigger the acceleration of the object. The more mass the object has, the more inclined it is to resist any change to its motion. For example, if you apply the same unbalanced force to a mass of.
