What is speed?

Speed is a measure of how fast an object is moving

100

What is net force ?

 The net force refers to the sum of all the forces acting on an object.

100

what is convection ?

the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat:

  1. What is a net force and how is it calculated?



The net force is the vector sum of all forces acting on an object. It is calculated by adding together all forces acting in one direction

which of the following is an insulator?

A. Metal B. Copper c. Rubber D. Bronze 

Option C. Rubber

what is acceleration ?

Acceleration is the rate at which an object’s velocity changes over time, considering both speed and direction. It can mean speeding up, slowing down, or changing direction. It’s a vector quantity, meaning it has both magnitude and direction

200
What is displacement?

Change in position of an object

200

what is adding force?

Adding Forces: Forces can be added together using vector addition. This concept has been central to physics since the times of Galileo and Newton. When adding forces, we use the “tip-to-tail” method. For example, if two forces

2. How do multiple forces acting on an object interact to create a net force?

 

Ans 2. When multiple forces act on an object, they interact to create a net force which is the vector sum of all individual forces. If the forces are in the same direction, they add up to make the net force stronger.

What are conductors?

Conductors are materials or substances that allow the flow of electricity, heat or sound through them

300

Formula of acceleration?

a = F/m

300

what is the difference between potential and kinetic energy?

Potential energy is the energy that an object has due to its position or condition, such as gravitational potential energy Kinetic energy, on the other hand, is the energy that an object possesses due to its motion.

300

What is vector quantity?

Vector Quantity: A force is considered a vector quantity, which means it has both magnitude (size) and direction.

300
  1. What is the difference between a balanced and unbalanced net force?

If the forces exerted on the object are balanced, then the net force will be zero, as the two individual forces cancel out each other and will not result in the change in its state of rest/motion. Unlike, if the applied force on an object is unbalanced, then the net force will be non-zero, which result in the change in its state.

what is a series circuit?

Most simple type of electrical circuit Batteries, Resistors, Capacitors, Solenoids, etc...

400

Formula of speed ?

Speed = distance/time

400

what is radiation?

Radiation is the emission or transmission of energy in the form of waves or particles

400

What are time graphs?

A time graph is a type of visualization of time-series data where the data points are arranged in a grid1

400

How does the direction of forces affect the calculation of a net force?

Net force is equal to gravity plus wind. Since the net force is now pointing down and to the right, that also dictates the direction that that particle will accelerate. I

How are insulators and conductors used in everyday electrical systems?


Insulators are used in electrical systems to prevent the flow of electricity. They are typically made of materials that do not conduct electricity well, such as rubber, plastic, or glass. Insulators are used to protect workers and prevent electrical hazards by keeping electrical currents confined to specific pathways.

Conductors, on the other hand, are materials that allow electricity to flow freely. They are typically made of metals like copper, aluminum, and silver, which have low resistance to electrical current. Conductors are used in power lines, electrical wiring, and electronic devices to carry electricity from one point to another. Conductors are essential for transmitting electricity efficiently and safely in everyday electrical systems.

What is kinetic energy ?

energy which a body possesses by virtue of being in motion.

500

What is potential energy?

Potential energy is the energy an object possesses due to its position relative to other objects, internal stresses within itself, electric charge, or other factors.

500

what is parallel circuits?

Connecting electrical components on separate branches.
