# What Is Torque Class 11?

Torque is the measure of the force that can cause an object to rotate about an axis. Force is what causes an object to accelerate in linear kinematics. Similarly, torque is what causes an angular acceleration. Hence, torque can be defined as the rotational equivalent of linear force.

### What is pressure and it's SI unit?

Unit of pressure: pascal (Pa)

Pressure is the amount of force applied perpendicular to the surface of an object per unit area and the for it is p (or P). The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m1·s2).

### Can a body possess energy even if it is not in motion?

Yes, a body can possess energy when it's not in motion. For example - Water store in the dam is not in motion and possesses potential energy.

### What is the relation between kinetic energy and momentum Class 11?

In a constant object, momentum increases directly with speed whereas kinetic energy increases the square of the velocity due to energy momentum relation.

kilogram-force

### Which energy transferred if a body is acted upon by a force normal to the direction of displacement?

Yes, there is no transfer of energy if the body is acted upon by the force normal to the displacement. When the body is moving in a circular path, the force is normal to its displacement and the work done is zero. Thus, there is no transfer of energy. The unit kWh is the unit of energy.

### What happens to the potential energy when a body falls from a height of 2 m and comes to rest?

Explanation: potential energy decreases as it depends on the height so, if "h" is reduced PE will also reduced.

### What is force in physics class 10?

In Physics, force is defined as: The push or pull on an object with mass that causes it to change its velocity. Force is an external agent capable of changing the state of rest or motion of a particular body. It has a magnitude and a direction.

### What is force Vedantu?

Force is a push or a pull that changes or tends to change the state of rest or uniform motion of an object or changes the direction or shape of an object. It causes objects to accelerate. SI unit is Newton.

### What is work-energy theorem BYJU's?

According to this theorem, the net work done on a body is equal to change in kinetic energy of the body. This is known as Work-Energy Theorem. It can be represented as. Kf – Ki = W.

### What is Work energy theorem Class 10 ICSE?

According to the work-energy theorem, the work done by a force on a moving body is equal to the increase in its kinetic energy.

### What is torque class 11?

Torque is the measure of the force that can cause an object to rotate about an axis. Force is what causes an object to accelerate in linear kinematics. Similarly, torque is what causes an angular acceleration. Hence, torque can be defined as the rotational equivalent of linear force.

### What is the relation between Ke and momentum?

Relation Between Momentum and Kinetic Energy

If the Momentum(p) is constantK . E ∝ 1 m
If Kinetic Energy(K.E) is constantp ∝ m
If mass(m) is constantp ∝ K . E

### How do you convert kinetic energy into momentum?

The relationship between kinetic energy and momentum is given by the equation T=p2/2m, where T is kinetic energy, p is momentum and m is mass. This relationship comes directly from the definitions of momentum (p=mv) and kinetic energy (T=½mv2).

### What is moment of force for Class 10?

The moment of force is equal to the product of the magnitude of the force and the perpendicular distance of the line of action of force from the axis of rotation. S.I. unit of moment of force is Newton metre (Nm).

### How kinetic energy is derived?

The kinetic energy of a body is the energy that it possessed due to its motion. Kinetic energy can be defined as the work needed to accelerate an object of a given mass from rest to its stated velocity.
