Mass is measured in ​ (a)   often written as ​ (b)  

• kilograms
• Newtons
• Metres
• kg
• N
• m

Weight is measured in

On bigger planets your mass will:

• increase.

• stay the same.

• decrease.

• multiply by 2.

Weight is described as ​ (a)   pull on an object.

• gravity's
• the sun's
• the moon's
• friction's
