Which statement best states the relationship between mass and gravitational attraction between two objects?

• The less mass an object has, the greater its gravitational force.

• The more mass an object has, the greater its gravitational force.

Calculate the weight (in newtons) of a 100kg person on Earth.

• 100 x 98= 9,800 Newtons

• 9.8m/100 kg= 0.098 Newtons

• 10kg X 9.8m/s2 =

  98 Newtons

• 100 kg X 9.8 m/s2=

  980 Newtons

The acceleration of gravity is 28 times greater on the Sun than on Earth. Imagine there is a spacesuit that would let a person stand on the surface of the Sun. Calculate the weight (in newtons) of a 100 kg person on the Sun. (Remember gravity on Earth is 9.8 m/s2.)

• 2,800 Newtons

• 27,440 Newtons

• 37,440 Newtons

The (a)   of an object does not change when it is taken to another planet.

The mass of an object does not change when it is taken to another planet, but its (a)   may be different on that planet if that planet's mass is different from Earth.
