### Unbalanced Force: Definition & Example - Video & Lesson Transcript ...

Balanced forces do not cause a change in motion. When balanced forces act on an object at rest, the object will not move. If you push against a wall, the wall pushes back with an equal but opposite force. Neither you nor the wall will move. Forces that cause a change in the motion of an object are unbalanced forces.

### Balanced and Unbalanced Forces - The Physics Classroom

www.physicsclassroom.com > Physics Tutorial > Newton's Laws If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced. An object is said to be acted upon by an unbalanced force only when there is an individual force that is not being balanced by a force of equal magnitude and in the opposite direction.

### Unbalanced forces - BBC

www.bbc.co.uk/bitesize/ks3/science/energy_electricity_forces/forces/revision/6/ When two forces acting on an object are not equal in size, we say that they are unbalanced forces. If the forces on an object are unbalanced this is what happens: an object that is not moving starts to move. an object that is moving changes speed or direction.

### Why is Isaac Newton famous?

He is one of the few acknowledged geniuses in the history of science. There is argument about who qualifies beyond he and Einstein, to a greater or lesser degree, but not about these top 2.

Newton was a polymath too, an all-round genius. He is responsible for
- the laws of motion
- the law of universal gravitation
- proving Kepler's Laws of Planetary Motion
- the first theory of colour and spectrum
- the first practical reflecting telescope
- jointly with Leibniz, the mathematical calculus

He was famous in his own time, but was not always an attractive person, being sometimes cranky, argumentative and ungenerous.

Lagrange said Newton amongst scientists was "the most fortunate, for we cannot find more than once a system of the world to establish."

### A 50-kg block rests at the top of a smooth inclined plane whose length is 2 m and whose height is 0.50 m.How long will it take for the block to slide to the bottom of the plane when released?

If the block is at rest it will never get to the bottom unless someone gives it a push.
Newton's 1st Law of Motion.......
The velocity of a body remains constant unless the body is acted upon by an external force.

### Why is the air coming out is cold

Because a dehumidifier is actually a air conditioner that runs very 'poorly' The way to get the water out of the air is to have a difference in temperatures ... remember in the 4th grade science class when the teacher talked about the DEW point? That natural law applies here.

Secondly, air i motion generally feels cooler than air not in motion. It is one of Newtons laws (I think)

Thanks for visiting today.

### The middle arm on my Evolution dishwasher isn't spinning - the top and bottom one seem fine. Glasses especially on top shelf aren't getting clean at all (obviously!). Any suggestions?

Check if the holes are blocke dwith dirt the arms spin by newtons law that every action has a reaction (like a rocket) if the holes are blocked it wont spin as there is no force.

### Who discover law of gravity

Isaac Newton discovered the Law Of Gravity. You can check more about Law of Gravity here... (click here).

If you need further help, let me know.

Good luck.

### How much force would she experience if she stopped in 0.2 seconds because she hit a brick wall?

Newton's law of action/reaction

The force would be the same is the answer

In any collision, there are always four quantities which are the same for both objects involved in the collision. Each object experiences the same force (Newton's third law) for the same amount of time, leading to the same impulse, and subsequently the same momentum change. Only the acceleration and the velocity change can differ for the two objects. The object with the least mass always receives the greatest velocity change and acceleration.

You brought back memories from when I was in college at UNC
