The speed-time graph for an object is shown.
Below are four statements about the acceleration of the object.
Which statement is correct?
An object tends to keep moving with the same speed and in the same direction due to a certain property.
The object also has weight due to the action of a field.
What is the name of the property, and what is the name of the field?
[Table] property | field
A | mass | electric
B | mass | gravitational
C | volume | electric
D | volume | gravitational

The diagram shows a gas that is trapped in a cylinder by a piston. The volume of the gas is 120 cm$^3$ and the pressure of the gas is $P$.
The piston is moved slowly to the left so that the volume of the gas is reduced to 30 cm$^3$. The temperature of the gas does not change.
What is the new pressure of the trapped gas?

On a very cold day, a boy puts one hand on the metal handlebars of his bicycle. He puts the other hand on the rubber hand grip.
The metal feels colder than the rubber hand grip, although they are both at the same temperature.
Why is this?
