2.4 kg
0 kg
1.2 kg
4.8 kg

No test object is present at a point above a planet. Which statement about the gravitational field there is correct?

The field exists because a mass placed there would experience gravitational attraction.
The field appears only when a test object is placed there.
The field is material stored inside a test object.
The field cannot extend through empty space.

A 5.0 kg package is where gravitational field strength is 4.0 N/kg. Which record correctly interprets the field strength and gives the package's mass and weight?

Each kilogram experiences 4.0 N; mass 5.0 kg; weight 20 N.
Each kilogram experiences 0.25 N; mass 5.0 kg; weight 1.25 N.
Each kilogram experiences 4.0 N; mass 5.0 N; weight 20 kg.
Every object experiences 4.0 N; mass 5.0 kg; weight 4.0 N.

96 kg/m³
240 kg/m³
2400 kg/m³
9600 kg/m³

A perpendicular force of 600 N acts uniformly over 0.030 m². Which option gives both the pressure and its meaning?

20 000 Pa; pressure is perpendicular force per unit area.
20 Pa; pressure is area per unit perpendicular force.
18 Pa; pressure is perpendicular force multiplied by area.
20 000 N; pressure is the total force on a surface.

A toy car is pulled by a taut string while a nearby magnet repels a magnet fixed to the car. How should the two forces be classified?

Tension is contact; magnetic force is non-contact.
Tension is non-contact; magnetic force is contact.
Both forces are contact.
Both forces are non-contact.

A sealed 9.0 kg toolkit is moved from one shelf to another without adding or removing material. What is its mass after the move?

0 kg
Less than 9.0 kg because its position changed
9.0 kg because the amount of matter is unchanged
More than 9.0 kg because it travelled

No probe is currently placed at a point above Earth. Which statement about Earth's gravitational field at that point is correct?

The field still exists because Earth would exert force on a mass placed there.
The field exists only after a probe is placed there.
The field disappears whenever the point is empty.
The field is a force stored inside the probe.

4.0 N per kilogram; mass 3.0 kg; weight 12 N
0.25 N per kilogram; mass 3.0 kg; weight 0.75 N
4.0 N per kilogram; mass 3.0 N; weight 12 kg
4.0 N on every object; mass 3.0 kg; weight 4.0 N

0.000054 kg/m³
240 kg/m³
2400 kg/m³
24 000 kg/m³

A normal force of 450 N acts uniformly over 0.090 m². Which option gives the pressure and interprets it correctly?

5000 Pa; 5000 N of normal force per square metre
40.5 Pa; normal force multiplied by area
0.00020 Pa; area divided by normal force
5000 N; the total force without reference to area

A small test mass is placed to the right of an isolated planet. In which direction does the planet's gravitational field act at the test mass?

Towards the planet
Away from the planet
Vertically upward on the page
There is no direction because a field is not a force

650 g
325 g
1300 g
650 N
