Year 7 Science - Gravity, mass and weight

Which objects have a STRONG force of gravity?

• Objects with GREATER mass, like elephants
• Objects with LESS mass, like mice

As the distance between two objects increases, the pull of gravity ...

• ... increases.

• ... decreases.

• ... stays the same.

The force of gravity acting on an object is the object's ...

• mass
• matter
• weight 
• friction 

The amount of matter in an object is the object's ...

• pressure
• weight
• mass
• force

Which of the following never changes no matter where in the universe?

• weight
• force
• mass
• pounds

A person would weigh less on on the Moon than on the Earth because . . .

• Moon has more mass, and therefore more gravity
• Moon has less mass, and therefore more gravity
• Moon has more mass, and therefore less gravity
• Moon has less mass and therefore less gravity

Two factors effecting the magnitude of the force of gravity between 2 objects are...

• mass and distance 
• mass and matter
• distance and weight 
• weight and mass

If Earth's mass was cut in half, what would happen to your mass?

• increase because gravitational force increases
• decrease because gravitational force decreases
• decrease because gravitational force increases
• nothing, mass is not affected by gravitational force

Which model has greater gravitational attraction (if any)

• Model A
• Model B
• Both Model A and Model B (same gravity)

The scientific unit of weight is

• Kg
• N
• pounds
• Kgm/s
