Which statement about the mass and the weight of an object is correct?
They are both affected by changes in the acceleration of free fall.
They are both forces.
They have different units.
Weight is calculated by dividing mass by the acceleration of free fall.

A helium balloon is tied to a top-pan balance. A metal block of mass 100 g is placed on the balance. The reading on the balance is 91 g.
Which statement can be deduced from this experiment?
The balloon exerts a downward force of 0.09 N on the top-pan balance.
The helium has a mass of –9 g.
The helium has a mass of +9 g.
The resultant downward force on the top-pan balance is 0.91 N.
A box of mass 2.0 kg is pulled across the floor by a force of 6.0 N.
The frictional force acting on the box is 1.0 N.
What is the acceleration of the box?
0.40 m/s2
2.5 m/s2
3.0 m/s2
3.5 m/s2

Which name is given to the force that stretches the spring?
friction
mass
pressure
weight
A body of mass m has a weight W in a location where the gravitational field strength is g.
Which statement about these quantities is correct?
m and W are both forces.
m and W are both vector quantities.
m and W are related by the equation (W/m) = g
m and W have the same unit
Each diagram shows a metal plate with four parallel forces acting on it. These are the only forces acting on the plates.
