Physics Forces Quiz

What are the three types of forces discussed in the video?

• Weight, Friction, Tension

• Weight, Normal Reaction Force, Tension

• Normal Reaction Force, Friction, Tension

• Weight, Friction, Normal Reaction Force

How is weight defined in terms of force?

• Weight is the mass of an object.

• Weight is the acceleration of an object.

• Weight is the force due to gravity acting on an object.

• Weight is the volume of an object.

What is the unit of weight in the metric system?

• Pounds

• Kilograms

• Newtons

• Grams

How does weight differ from mass?

• Weight is a measure of matter, mass is a force.

• Weight is constant everywhere, mass changes with location.

• Weight is measured in kilograms, mass in newtons.

• Weight changes with gravitational field, mass remains constant.

What happens to the weight of an object on the moon compared to Earth?

• It decreases.

• It becomes zero.

• It remains the same.

• It increases.

What law is the normal reaction force associated with?

• Newton's First Law

• Newton's Second Law

• Newton's Third Law

• Law of Universal Gravitation

How does the normal reaction force act on a surface?

• Parallel to the surface

• Perpendicular to the surface

• At an angle to the surface

• In the direction of gravity

What symbol is commonly used to represent tension force?

• F_g

• F_n

• R

• F_t

In which direction does tension force act?

• In any random direction

• Opposite to the direction of the rope

• In the direction of the rope or chain

• Perpendicular to the rope

What is the primary characteristic of tension force?

• It only pushes.

• It can push and pull.

• It neither pushes nor pulls.

• It only pulls.
