5. Tension force

What is tension force?

• The force exerted by a surface perpendicular to an object in contact with it
• The force exerted by a rope when pulled
• The force that opposes motion due to the contact between surfaces
• The force that pulls an object downwards

What law explains normal reaction?

• Newton's First Law
• Newton's Second Law
• Newton's Third Law
• Newton's Fourth Law

What happens when a wooden block is pulled with a string?

• Weight and normal reaction are equal and opposite
• The weight of the block increases
• The normal reaction disappears
• The wooden block falls apart

What creates opposing force according to Newton's third law?

• Friction
• Weight
• Applied force
• Inertia

What is tension force in a string?

• The pulling force that occurs in the string
• The force that pulls an object downwards
• The force that opposes motion due to the contact between surfaces
• The force that opposes the motion of an object in a fluid

What creates tension in an element?

• Weight
• Friction
• The force transmitted axially
• Inertia

Which force is demonstrated through a man pulling a rope in the illustrated example?

• Friction force
• Tension force
• Applied force
• Normal reaction force

What is normal reaction?

• The force that pulls an object downwards
• The force exerted by a rope when pulled
• The force that opposes motion due to the contact between surfaces
• The force exerted by a surface perpendicular to an object in contact with it

What does tension force act on?

• Two surfaces in contact
• A fluid in motion
• An object in motion
• A string that is being pulled

How can the force in an element be measured?

• By its weight
• By its length
• By its color
• By its temperature
