Beta
Gamma
Neutron
9 of 24
Which type of nuclear radiation is most penetrating?
Gamma
10 of 24
Which type of nuclear radiation is least penetrating?
Alpha
11 of 24
Why does alpha radiation have a low
penetrating power?
Alpha has a high mass which means it is more likely to collide with other particles and lose momentum.

What's the equation for weight regarding mass and gravitational field strength?
weight = mass x gravitational field strength
17 of 24
What's the equation for speed?
Speed = distance ÷ time
18 of 24
What's the difference between a scalar and
vector quantity?
A scalar quantity has a magnitude but a vector quantity has a magnitude and direction.
19 of 24
