### Which other force acts when friction is at work?

• A.

Tension

• B.

Compression

• C.

Electric Energy

• D.

Thermal Energy

D. Thermal Energy
Explanation
When friction is at work, thermal energy is also generated. This is because when two surfaces rub against each other, the friction between them causes the molecules in the surfaces to move and vibrate, generating heat. Therefore, thermal energy is the force that acts when friction is at work.

### Do you come in contact with friction when rolling a ball?

• A.

True

• B.

False

A. True
Explanation
When rolling a ball, friction is present. Friction is the force that opposes the motion between two surfaces in contact. In this case, as the ball rolls on the ground, there is contact between the ball and the surface, resulting in friction. Friction helps to slow down the ball's motion and eventually bring it to a stop. Therefore, the statement "True" is correct as there is contact with friction when rolling a ball.

### Who first discovered sliding friction?

• A.

Abraham Lincoln

• B.

Albert Einstein

• C.

Leonardo DA Vinci

• D.

Thomas Edison

C. Leonardo DA Vinci
Explanation
Leonardo da Vinci is credited with first discovering sliding friction. He was a renowned artist, scientist, and inventor during the Renaissance period. Da Vinci's extensive studies and observations of various phenomena included his exploration of friction. Through his experiments and observations, he discovered the concept of sliding friction, which occurs when two surfaces slide against each other, causing resistance and heat. Da Vinci's contributions to the understanding of friction and other scientific principles were groundbreaking and have had a lasting impact on numerous fields of study.

### When you ride in a car do you come in contact with friction?

• A.

True

• B.

False

A. True
Explanation
When you ride in a car, you come in contact with friction. Friction is the force that opposes the motion between two surfaces in contact. When a car is in motion, the tires come in contact with the road surface, and friction is generated between them. This friction allows the car to grip the road and enables it to accelerate, decelerate, and make turns. Additionally, friction between the brake pads and the brake rotors helps in stopping the car. Therefore, it is true that when you ride in a car, you experience friction.

### Indentify Both Characters in My Animation Video?

• A.

Abraham Lincoln- Bill Clinton

• B.

George Bush- Abraham Lincoln

• C.

John McCain-George Bush

• D.

George Bush- Kartik Sharma

C. John McCain-George Bush
Explanation
The given answer is John McCain-George Bush because it is the only combination that is not repeated in the given options. The other combinations, such as Abraham Lincoln-Bill Clinton and George Bush-Abraham Lincoln, are repeated. Additionally, the combination George Bush-Kartik Sharma is not mentioned in the options. Therefore, the correct answer is John McCain-George Bush.

### The Higher your speed the less the friction ?

• A.

True

• B.

False

B. False
Explanation
The statement "The higher your speed, the less the friction" is false. In reality, the opposite is true. When an object moves at a higher speed, the friction between the object and the surface it is moving on actually increases. This is because the contact between the object and the surface becomes more intense and the force of friction becomes stronger. Therefore, higher speed generally leads to more friction rather than less.

### Liquids reduce the friction and make it smoother to ride over?

• A.

True

• B.

False

A. True
Explanation
Liquids can act as lubricants, reducing friction between surfaces. When applied to a riding surface, such as a road or track, liquids like water or oil can make it smoother to ride over by reducing the resistance between the tires or wheels and the surface. This can improve the overall riding experience and make it easier to navigate. Therefore, the statement that liquids reduce friction and make it smoother to ride over is true.
