1A [blank_start]body[blank_end] stays at [blank_start]rest[blank_end], or if moving it continues to move with [blank_start]uniform[blank_end] velocity, unless an [blank_start]external[blank_end] force makes it [blank_start]behave[blank_end] differently.

2The mass of a body measures its inertia.

31N = [blank_start]1 kg m/s^2[blank_end]

5Newton's second law states that [blank_start]force[blank_end] = [blank_start]mass[blank_end] x [blank_start]acceleration[blank_end], when the force is in [blank_start]newtons[blank_end], the mass in [blank_start]kilograms[blank_end] and the acceleration is in [blank_start]metres per second squared[blank_end].

- Dnewtons
- Ekilograms
- Fmetres per second squared
6When using Newton's [blank_start]second[blank_end] law, [blank_start]two[blank_end] points should be noted. The law also shows that [blank_start]a[blank_end] will be largest when [blank_start]F[blank_end] is large and [blank_start]m[blank_end] small.

7Weight = [blank_start]mass[blank_end] x [blank_start]acceleration of free fall[blank_end]
- Amass

9The [blank_start]strength[blank_end] of a gravitational field is defined as the [blank_start]force[blank_end] acting on unit [blank_start]mass[blank_end] in the field.
- Astrength
- Bforce
- Cmass
10N/kg = [blank_start]m/s^2[blank_end]
- Am/s^2
11'g' can be described as acceleration of free fall or as the Earth's gravitational field.
- AVerdadero
- BFalso
12An object's constant velocity is called [blank_start]terminal[blank_end] velocity.
