Daily Practice - GCSE Science
Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
- 1Atomic Structure
What is an alpha particle made of?
- 2Atomic Structure and the Development of the Model
Who provided the evidence for the existence of the neutron, and roughly when relative to the nuclear model?
- 3Radioactivity, Half-Life and Nuclear Uses
Radium-226 (atomic number 88) decays by alpha emission. State the atomic number of the nucleus formed.
- 4Forces
A box has a driving force of 250 N forward and friction of 180 N backward. Calculate the resultant force, including its direction.
- 5Motion: Speed, Velocity and Acceleration
A ball decelerates uniformly from 18 m/s to 0 m/s over a distance of 2.7 m while being caught. Using (final velocity)^2 = (initial velocity)^2 + 2 x acceleration x distance, calculate its deceleration.
