Questions and Answers

Which cylinder and water level combination should be used for an accurate measurement?

Smaller cylinder at the bottom of the meniscus

Smaller cylinder at the top of the meniscus

Larger cylinder at the top of the meniscus

Larger cylinder at the bottom of the meniscus (correct)

If a gas is contained in a cylinder and the volume is decreased while temperature remains constant, what happens to the pressure of the gas according to gas laws?

Pressure decreases

Pressure increases (correct)

Pressure remains the same

Pressure is negligible

What is the relationship between density, mass, and volume?

Density is mass multiplied by volume

Density is constant regardless of mass and volume

Density is mass divided by volume (correct)

Density is the square of mass over volume

Study Notes

Speed-Time Graphs

A graph representing an object moving with an increasing speed will have a line that is sloping upwards
The gradient of a speed-time graph represents the acceleration of an object
The area under a speed-time graph represents the distance travelled

Weight and Gravitational Field Strength

The weight of an object is the force exerted on it due to gravity
The gravitational field strength is the gravitational force per unit mass
The weight of an object can be calculated by multiplying its mass by the gravitational field strength

Measuring Volume

The bottom of the meniscus should be used to measure the volume of a liquid in a graduated cylinder
The smaller the cylinder the more accurate the measurement will be

Motion on The Moon

All objects fall with the same acceleration on the Moon due to the Moon's lower gravitational field strength
