Daily Practice - GCSE Science
Biology, chemistry and physics recall, definition and calculation, drawn from every strand.
- 1Atomic Structure
What happens inside the nucleus when a beta particle is emitted?
- 2Atomic Structure and the Development of the Model
What observation showed the nucleus is positively charged and very small?
- 3Radioactivity, Half-Life and Nuclear Uses
State one source of natural background radiation and one source of artificial (man-made) background radiation.
- 4Forces
Calculate the weight of an object of mass 8.0 kg on Earth, where g = 9.8 N/kg.
- 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.
