What is the definition of an unbalanced force?

Answers

an unbalanced force is Forces that are not equal

Final answer:

An unbalanced force occurs when the forces acting on an object are not equal and opposite, causing a change in the object's motion. This is dictated by Newton's second law of motion. When forces are balanced, the object remains at rest or continues its motion unchanged.

Explanation:

An unbalancedforce refers to a scenario in which the forces acting on an object are not equal in magnitude and direction, causing a change in the motion of the object. In accordance with Newton's second law of motion, the motion change is directly proportional to the total unbalanced force and occurs in the direction of that force. Exceptionally, if the forces acting on an object are balanced, the object will either stay at rest or continue moving with a constant velocity, since the net force equals zero.

Consider this simple example to illustrate the principle. If you push a table to the right with a force of 10 Newtons and nothing pushes back with an identical force, the unbalanced force causes the table to move to the right. This is because there is an unbalanced force exerted upon it. Conversely, if an equal force of 10 Newtons is applied to the table from the opposite direction, these forces are balanced, and the table remains stationary because the net force is zero.

A stone thrown from a height of 5.72 meters hits the ground at 13.3, Calculate the initial speed. Neglect air resistance

Answers

Answer:

12.31618 m/s

Explanation:

s = Displacement

t = Time taken

g = Acceleration due to gravity = 9.81 m/s² = a

$s=ut+(1)/(2)at^2\n\Rightarrow 5.72=0t+(1)/(2)* 9.81* t^2\n\Rightarrow t=\sqrt{(5.72* 2)/(9.81)}\n\Rightarrow t=1.07988\ s$

Velocity is given by

$v=(s)/(t)\n\Rightarrow v=(13.3)/(1.07988)\n\Rightarrow v=12.31618\ m/s$

The initial velocity is 12.31618 m/s

What is the mass of a falling rock if it produces a force of 147 N with an acceleration of 9.8 m/s2?

Answers

Answer:

15 kg

Explanation:

The mass of the object can be found by using the formula

$m = (f)/(a) \n$

f is the force

a is the acceleration

From the question we have

$m = (147)/(9.8) \n$

We have the final answer as

15 kg
