Choose two

• Speed

• Acceleration

• Energy

• Weight

Which of these are vector qualities?

Choose two

• Speed

• Acceleration

• Energy

What is the difference between vector and scalar measurements?

• Scalar is measured in Newtons, vector is measured in Grams

• Scalar is magnitude, vector is direction

• Scalar is magnitude, vector is magnitude and direction

• Scalar is a bigger measurement than vector
