# What does the word tangent mean?

## What does the word tangent mean?

1. What touches, what touches. 2. [ Geometry ] That touches a line or surface at a single point.

## How does centripetal force work?

**Centripetal force**is the resultant

**force**that acts on a body and describes a movement in a circular path. It is responsible for changing the direction of the body’s speed and, in addition, it always points towards the center of the curves, so that the angle formed between this

**force**and the velocity vector is always 90º.

## What is centripetal force?

This is the force that acts on objects in circular paths. It is defined by Newton’s second law. When an object performs a uniform circular **motion** , the value of its speed is constant, but this quantity undergoes changes in its direction.

## What is the value of the centripetal force acting on the assembly?

In the direction of the trajectory radius, the **centripetal force** is given by the sum of the **forces** acting on the body. Worked example: Consider the image of the globe of death and the data: r = 2.0 m; m = 150 kg (man + motorcycle) and v = 6.0 m/s (speed at the highest point).

## How does centripetal force work in the globe of death?

Centripetal force **is the “resultant” force** toward the center – you might think of it **as** always the “toward” **force** minus the “outward” **force** . When the biker is at the lowest point, notice that the normal points towards the center and the weight “outwards”, so the **centripetal force** ends up being Fc = N – P.

## What is the secret of the globe of death?

**globe of death**is subject to falling when it is at its highest point, so that this does not happen it is necessary to have a minimum speed at that point. … We can see that the minimum speed to take a safe ride only depends on the size of the

**globe**, and not on the masses of the rider and the bike.

## What is the formula for calculating the work done by a force?

How is **the work** of a **force** calculated ? To calculate the **work** exerted by a constant **force** , it is necessary to multiply the modulus of that **force** by the distance traveled and by the cosine of the angle formed between the **force** (F) and the distance (d).

## What is Centripetal force Brainly?

Answer: **Centripetal force** is the resultant **force** that pulls the body towards the center of the trajectory in a curvilinear or circular motion. Objects that move in uniform rectilinear motion have constant modular speed. … The reason for this change in speed is **centripetal** acceleration .

## How to calculate work in Thermodynamics?

**Thermodynamics**is given by ΔU = Q – W, where ΔU is the variation in the internal energy of the gas, Q is the energy transferred in the form of heat and W is the

**work**done by the gas, it is correct to state that: a) The gas pressure increased and the temperature decreased.

## How do you calculate the displacement of a body?

In the formula above, ΔS is called **displacement** and measures the distance between the final (Sf) and initial positions of a piece of furniture (S0), therefore, ΔS = Sf – S0. The time interval elapsed between the furniture passing through the initial and final positions is given by Δt, calculated by the expression Δt = tf – t0.

## What is the work done by a force?

In Physics, therefore, we define the **work done by a force** as being the product of the **force** and the displacement. As **force** and displacement are vector quantities, **work** is defined as the scalar product of **force** and displacement.

## What is the purpose of calculating the work of a force?

**calculate the work**that a

**force**does on a moving object, we only use the component of the

**force**along the object’s displacement. The component of the

**force**perpendicular to the displacement produces zero

**work .**

## What is the work done by the weight force?

Therefore, the **work done by the weight force** in a vertical displacement Δh can be calculated by the following expression: **Work force weight** = mass × local gravity acceleration × height variation.

## What is resistant work?

When a body is falling, the **work** of the weight force is motor, as it acts in the same direction as the displacement. If, on the contrary, the body is rising, the **work** is **resistant** , as the weight acts in the opposite direction of the displacement.

## What is the difference between motor work and resistant work?

Response. Answer: When the displacement occurs in the same direction as the component of the force that acts on the displacement, the **work** is **motor** . On the contrary, when it occurs in the opposite direction, the **work** is **resistant** .

## What does a negative job mean?

A force does **positive work** if it has a vector component in the same direction as the displacement, and it does **negative work** when it has a vector component in the opposite direction. The force has zero **work** when it does NOT have a vector component in the direction of displacement.

## What is the definition of work according to physics? What’s the difference?

Answer: Explanation: **WORK ACCORDING TO PHYSICS** IS EQUAL TO FORCE: “FORCE IS AN ACTION CAPABLE OF CAUSING CHANGES IN THE MOVEMENT OF A BODY”. **WORK ACCORDING** TO COMMON SENSE: ” **WORK** OF A FORCE IS THE AMOUNT OF ENERGY CONSUMED IN EXECUTING A TASK, WHETHER PAID OR NOT”.

## What is the definition of cartography Brainly?

Answer: **Cartography** is the area of knowledge responsible for the preparation and study of maps and cartographic representations in general.

## What is the difference between the use of the word work in physics and in our everyday lives?

In our **daily lives** , the **word work** is related to some activity or service performed by an individual that requires or does not require physical effort. In **Physics** , this term is related to the energy transferred through the application **of** a force that is capable **of** generating displacement.

## What is the meaning of the work?

The **concept** of **work** is generally understood as human activity carried out with the aim of producing a form of subsistence. Work is defined by Karl Marx as the **activity** in which human beings employ their strength to produce the means for their sustenance.

## What is work for you?
