Explanation

• The Sun is approximately 330,000 times more massive than the Earth.
• It means it has a mass of about 1.989 x 10^30 kilograms.
• The Earth has a mass of about 5.972 x 10^24 kilograms.

Explanation

• Increasing the weight is not a way to reduce friction.

Ways to reduce friction:

• Smoothing and polishing surfaces
• Reducing contact area
• Using oil and lubricants
• Using ball bearings and rollers

• Freezing (liquid to solid).
• Evaporation (liquid to gas).
• Condensation (gas to liquid).
