Acceleration Due to Gravity

Which statement is correct?

• Acceleration due to gravity is equal to 9.8 m/s/s and has the symbol g.

• Acceleration due to gravity is equal to 9.8 m/s/s and has the symbol a.

• Acceleration due to gravity is equal to 9.8 m/s and has the symbol g.

• Acceleration due to gravity is equal to 4.18 m/s/s and has the symbol Ga.

All objects in free fall (and ignoring air resistance) accelerate towards the earth at 9.8 m/s/s.

• Your weight would be more due to a greater gravitational pull.

• Your weight would be less due to a greater gravitational pull.

• Your weight would be less due to a smaller gravitational pull.

• Your weight would be less due to a smaller gravitational pull.
