Understanding Torque in Physics

What is the primary focus of the video tutorial introduced in the first section?

• Organic Chemistry

• General Physics

• General Chemistry

• High School Chemistry

How does torque relate to Newton's Second Law?

• Torque is unrelated to Newton's Second Law.

• Torque is analogous to force in Newton's Second Law.

• Torque is the same as mass in Newton's Second Law.

• Torque is the same as acceleration in Newton's Second Law.

What is the unit of torque in the SI system?

• Joule

• Newton

• Newton meter

• Watt

In the context of torque, what does the lever arm represent?

• The distance from the axis of rotation to the point of force application

• The weight of the object

• The total length of the object

• The speed of rotation

Why is it easier to open a door by pushing far from the hinge?

• Because it decreases the torque

• Because it increases the lever arm distance

• Because it reduces the force needed

• Because it increases the door's weight

What happens to the torque if the force applied is parallel to the lever arm?

• Torque is maximized

• Torque is minimized

• Torque is doubled

• No torque is generated

How can you increase the torque when using a wrench?

• By applying force at an angle

• By using a shorter wrench

• By using a longer lever arm

• By applying force closer to the bolt

What is the torque generated by a 220 Newton force applied perpendicular to a door 0.50 meters from the hinge?

• 55 Newton meters

• 10 Newton meters

• 110 Newton meters

• 220 Newton meters

If a force is applied at an angle of 30° to a door, how is the torque calculated?

• Using the full force value

• Using the cosine of the angle

• Using the sine of the angle

• Using the tangent of the angle

How many times greater is the torque generated by a 2-foot breaker bar compared to an 8-inch wrench?

• Twice as much

• Three times as much

• Four times as much

• Five times as much
