What is the relationship between force and Mass in physics?

F = m a Newton’s second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object’s mass multiplied by its acceleration.

What happens to the force of gravity when mass is doubled?

The change in the gravitational force would be proportional to the product of the changes in the masses of the two particles. If the mass of one particle doubled while the other remained the same, the force would double. If the mass of both doubled, the force would quadruple.

What happens if two bodies are twice as far apart?

If the two bodies were twice as far, the force would be 4 times less. In your case, if they were twice as near (or the distance between them is halved), the force increases by a factor of 4. You would also increase the force by this factor if you increased the product of the masses by 4.

How do you calculate force from mass and acceleration?

Force Equation. Newton’s second law states that force is proportional to what is required for an object of constant mass to change its velocity. This is equal to that object’s mass multiplied by its acceleration.

What is the difference between an object at rest and motion?

An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. In the statement of Newton’s first law, the unbalanced force refers to that force that does not become completely balanced (or canceled) by the other individual forces.

How many constant forces act on a 5 kg object?

Two constant forces act on a 5 kg object moving in the x-y plane.   Force F1is 25 N at 35 degrees while F2= 42 N at 150 degrees.   At time t = 0, the object is at the origin and has velocity of (4 i + 2.5 j) m/s.   (a) Express the two forces in unit-vector notation.   Use unit-vector notation for your other answers.

How many newtons is the net force acting on the object?

1. Free-body diagrams for four situations are shown below. For each situation, determine the net force acting upon the object. Click the buttons to view the answers. The net force is zero Newtons. All the individual forces balance each other (i.e., cancel each other out). The net force is 5 Newtons, left.
