What is the definition of a newton?

• The force producing an acceleration of 1 meter per second squared on a mass of 1 kilogram

• The energy required to move 1 kilogram over 1 meter

• The power needed to accelerate 1 kilogram by 1 meter per second

• The pressure exerted by 1 kilogram on a surface

What is the formula for force?

• Force = mass + acceleration

• Force = mass / acceleration

• Force = mass × acceleration

• Force = mass - acceleration
