AQA GCSE Physics - Forces - Revision

What is the equation that links distance, force and work done?

• work done (J) = force (N) x distance (m)

• work done (J) = force (Nm) ÷ distance (m)

• work done (KJ) = distance (m) ÷ force (N)

What is the equation that links extension, force applied to a spring and spring constant?

• force applied to a spring = spring constant x extension

• force applied to a spring = spring constant ÷ extension

• force applied to a spring = extension ÷ spring constant

What is the equation that links distance, time and velocity?

• velocity = time x distance

• velocity = distance ÷ time

• velocity = time ÷ distance

What is the equation that links acceleration, change in velocity and time?

• acceleration = change in velocity x time

• acceleration = change in velocity ÷ time

• acceleration = time ÷ change in velocity

What is the equation that links acceleration, mass, and resultant force?

• resultant force = mass x acceleration

• resultant force = mass ÷ acceleration

• resultant force = acceleration ÷ mass

What is the equation that links mass, momentum, and velocity?

• momentum = mass x velocity

• momentum = mass ÷ velocity

• momentum = velocity ÷ mass

What is the unit of work?

• Newton

• Joule

• Watt

• meter

What is the resultant force in this diagram?

• 17 N, right

• 17 N, left

• 23 N, right

• 12 N, up

What equation links distance, speed and time?

• speed = time ÷ distance

• speed = distance ÷ time

• speed = distance x time

• speed = time x distance

Which of these can be measured in meters per second (m/s)

• Distance

• Time

• Speed

• Acceleration
