Tension

The video tutorial explains how materials, such as ropes or cables, stretch slightly when under tension. It contrasts this with compression, another force, and notes that both are measured in Newtons.

What is an example of an object that can experience tension?

• A rope or cable

• A solid block

• A liquid container

• A gas cylinder

What happens to most materials when they are under tension?

• They remain unchanged

• They stretch slightly

• They compress

• They break immediately

Which statement is true about the stretching of materials under tension?

• All materials stretch a little

• Only some materials stretch

• All materials stretch significantly

• No materials stretch

Which of the following is the opposite of tension?

• Expansion

• Compression

• Rotation

• Vibration

In what units are forces like tension and compression measured?

• Watts

• Newtons

• Joules

• Pascals
