# At what angle is the normal force equal to the weight?

## At what angle is the normal force equal to the weight?

If the angle was 90 dg (a vertical wall) the normal force would be zero and the mass would be in free fall with acceleration of g.. If the angle was 0 deg, the normal force would simply be the total weight since all of the weight would be supported by the surface.

**What is FF in physics?**

The coefficient of friction is a number between 0 and 1 that tells you how much a specific surface resists the motion of another surface. In your reference tables you are provided an equation for the force of friction. Ff = μFN. where Ff is the force of friction (N) μ is the coefficient of friction.

### What is the 2 fastest thing in the world?

List of animals by speed

Rank | Animal | Maximum speed |
---|---|---|

1 | Peregrine falcon | 389 km/h (242 mph) 108 m/s (354 ft/s) |

2 | Golden eagle | 240–320 km/h (150–200 mph) 67–89 m/s (220–293 ft/s) |

3 | White-throated needletail swift | 169 km/h (105 mph) |

4 | Eurasian hobby | 160 km/h (100 mph) |

**What is the weakest fundamental force?**

Though gravity holds planets, stars, solar systems and even galaxies together, it turns out to be the weakest of the fundamental forces, especially at the molecular and atomic scales.

## How do you find normal force from weight?

The weight of an object equals the mass of the object multiplied by the acceleration of gravity. Multiply the two values together. In order to find the normal force, you need to multiply the weight of the object by the cosine of the angle of incline.

**Can you remove gravity?**

Gravity is Earth’s incredible mass pulling matter toward its center. It pulls down on me with around 200lbs of force. The only way to remove that is to make the chamber fall at gravity’s accelleration, or to exit the pull of Earth’s gravity completely. It is impossible to eliminate gravity.

### What is normal force equal to?

This supporting force acts perpendicular to and away from the surface. It is called a normal force, and it also goes by the name “apparent weight.” When objects rest on a non-accelerating horizontal surface, the magnitude of the normal force is equal to the weight of the object: N=mg.

**What is the strongest force on earth love?**

When scientists looked for a unified theory of the universe they forgot the most powerful unseen force. Love is Light, that enlightens those who give and receive it. Love is gravity, because it makes some people feel attracted to others.

## Is a black hole faster than light?

Using NASA’s Chandra X-ray Observatory, astronomers have seen that the famous giant black hole in Messier 87 is propelling particles at speeds greater than 99% of the speed of light.

**Which is the strongest and weakest force?**

Actually, gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity.

### What is inside a Blackhole?

A black hole is a tremendous amount of matter crammed into a very small — in fact, zero — amount of space. The result is a powerful gravitational pull, from which not even light can escape — and, therefore, we have no information or insight as to what life is like inside.

**Is normal force less than weight?**

In the left image the normal force is less than body weight, and acting horizontally. In the middle image the normal force is less than body weight and acting at an angle. In the right image the normal force on the drill is more than it’s own weight because Master Sgt. Sangster is also pushing down on the drill.

## Why is gravity 32?

Gravity will accelerate any object at a rate of 32 feet per second per second. What it means is that if we fall for one second we’ll reach a speed of 32 feet per second. After two seconds we reach 64 feet per second. The speed rises as the square root of height, but in direct proportion to time.

**Can we create a black hole?**

In principle, a black hole can have any mass equal to or above about 2.21×10−8 kg or 22.1 micrograms (the Planck mass). To make a black hole, one must concentrate mass or energy sufficiently that the escape velocity from the region in which it is concentrated exceeds the speed of light.
