Scalar means

• It has mass and direction

• It only has direction

• It only has direction

• It only has magnitude

What is the definition of a vector?

• It has both mass and direction

• It has both mass and displacement

• It has both magnitude and displacement

• It has both magnitude and direction

What is the definition of a force?

• A push or a pull that acts on an object due to the mass of another object causing gravity

• A push or a pull that acts on an object due to the interaction with another object

• A attraction that acts on an mass due to the weight interacting with another object

• A attraction that acts on an object due to the weight of another object

The units of force are:

• Joules

• Newtons

• Newtonmeters

• Newtons per meter squared

On a different planet you would(pick 2):

• have the same weight

• have a different mass

• have a different weight
