The gravitational field strength in space is smaller than on the Earth’s surface.
A rocket is used to launch a satellite from the Earth’s surface into space.
How are the mass and the weight of the satellite affected as the satellite moves away from the surface of the Earth and into space?
Both the mass and the weight are unaffected.
The mass decreases and the weight decreases.
The mass increases and the weight is unaffected.
The mass is unaffected and the weight decreases.

that contains 30 cm3 of water.
The reading on the measuring cylinder rises to 42 cm3.
What is the density of the metal?
0.81 g / cm3
2.8 g / cm3
7.5 g / cm3
8.5 g / cm3
A single force is applied to a body.
What cannot happen?
a change in the direction of the moving body
a change in the mass of the body initially at rest
a change in the position of the body initially at rest
a change in the speed of the moving body
There is no atmosphere on the Moon.
Two metal spheres of identical volume but different mass are at rest at the same height above the ground on the Moon. They are dropped at the same time.
How do the spheres move after release?
The sphere with the larger mass has a smaller acceleration.
The sphere with the larger mass hits the ground first.
The sphere with the smaller mass has a smaller acceleration.
The two spheres hit the ground together.
What is an expression for the moment of a force about a pivot?
distance the force moves from the pivot ÷ force
force × distance the force moves from the pivot
force × perpendicular distance of the force from the pivot
force ÷ perpendicular distance of the force from the pivot
Which statement about centre of mass is correct?
Objects with a centre of mass at the same height are less stable when the base is larger.
Objects with a centre of mass at the same height are more stable when the base is larger.
Objects with higher centres of mass and smaller bases are more stable.
Objects with identical bases are more stable when the centre of mass is higher.
