iGCSE Physics formulae (1-10)

What is the relationship between speed, distance and time?

• Speed = Distance x Time
• Speed = Time / Distance
• Speed = Distance / Time
• Speed = Distance + Time

mass x velocity = ?

How do you calculate the moment of a force?

• Moment of a force = Force x Perpendicular Distance
• Moment of a force = Force / Perpendicular Distance
• Moment of a force = Force + Perpendicular Distance
• Moment of a force = Force - Perpendicular Distance

Draw a formula triangle for the relationship between force, mass and acceleration

Which statement correctly describes the relationship between force, area and pressure?

• Pressure is directly proportional to force and inversely proportional to area.
• Area is directly proportional to pressure and inversely proportional to force.
• Force is directly proportional to pressure and inversely proportional to area.
• Pressure is directly proportional to area and inversely proportional to force.

density = mass / ?

What is the correct formula to calculate kinetic energy?

• KE = 0.5 x mass x velocity

• KE = mass x velocity^2

• KE = 0.5 x mass x velocity^2

• KE = mass x g x height

what is the relationship between work done, force and distance moved?

• Work done = Force / Distance
• Work done = Distance / Force
• Work done = Force x Distance
• Work done = Force + Distance

Which 2 values are needed to calculate the weight of an object?

• the mass of the object

• the gravitational field strength

• the objects height

• the objects velocity

Work done is the same as energy transferred

• True
• False
