What happens when multiple forces act upon an object?

They all combine to affect the object as if there were one single force. It's not hard to calculate the strength and direction of that one equivalent force. It can turn out to be zero. Then the group of several forces is said to be 'balanced'.

The object will move if the forces are unbalanced.

Newtons second tells you that when a net force (the unbalanced force) is applied to and object it will produce an acceleration (movement) in direct proportion to the force and in inverse proportion to the mass of the object.

What is the difference between prejudice and discrimination?
adoni [48]

Prejudice has to do with the inflexible and irrational attitudes and opinions held by members of one group about another, while discrimination refers to behaviors directed against another group. Being prejudiced usually means having preconceived beliefs about groups of people or cultural practices.

calculate the value of net force acting on given body?5N acting towards right & 15N force acting towards left on the brick.(
lys-0071 [83]

Answer:

The net force acting on the body is 10N directed to the left.

Explanation:

   Magnitude of force to the right = 5N

   Magnitude of force to the left  = 15N

Net force acting on the object and in what direction;

Solution:

It is the vector sum of all forces acting on a body. This net force is the single force that will replace the forces acting on a body;

  For the problem;

   Net force  = Force to the left + Force to the right

 Let us take left to be negative and right to be positive;

    Force to the left  = -15N

    Net force  = -15N + 5N  = -10N

The net force acting on the body is 10N directed to the left.

If it requires 8.0 J of work to stretch a particular spring by 2.0 cm from its equilibrium length, how much more work will be re
jenyasd209 [6]

Answer:

The amount of work done required to stretch spring by additional 4 cm is 64 J.

Explanation:

The energy used for stretching spring is given by the relation :

E = \frac{1}{2}kx^{2}           .......(1)

Here k is spring constant and x is the displacement of spring from its equilibrium position.

For stretch spring by 2.0 cm or 0.02 m, we need 8.0 J of energy. Hence, substitute the suitable values in equation (1).

8 = \frac{1}{2}\timesk\times k \times(0.02)^{2}

k = 4 x 10⁴ N/m

Energy needed to stretch a spring by 6.0 cm can be determine by the equation (1).

Substitute 0.06 m for x and 4 x 10⁴ N/m for k in equation (1).

E = \frac{1}{2}\times4\times10^{4}\times (0.06)^{2}

E = 72 J

But we already have 8.0 J. So, the extra energy needed to stretch spring by additional 4 cm is :

E = ( 72 - 8 ) J = 64 J
