1Air resistance has a greater effect on [blank_start]light bodies[blank_end] than on [blank_start]heavy bodies[blank_end].
- Alight bodies
- Bheavy bodies
2The air resistance to a light body is large when compared with the body's weight.
- AVerdadeiro
- BFalso
3Acceleration of free fall is denoted by the italic letter '[blank_start]g[blank_end]'.
- Ag
4In calculations involving motion, 'acceleration of free fall' replaces 'acceleration'.
- AVerdadeiro
- BFalso
5Rising bodies are denoted by a negative sign as they are decelerating.
- AVerdadeiro
- BFalso
6For a body falling freely from rest, we have [blank_start]s = 1/2gt^2[blank_end]. When '[blank_start]s[blank_end]' denotes distance and '[blank_start]t[blank_end]' denotes time. When '[blank_start]s[blank_end]' is against '[blank_start]t^2[blank_end]', the distance-time graph shows a constant plot, while against '[blank_start]t[blank_end]', it shows a [blank_start]non-constant[blank_end] plot.
- As = 1/2gt^2
- Bs
- Ct
- Ds
- Et^2
- Ft
- Gnon-constant
7The horizontal and vertical motions of a body are indepedent and can be treated separately.
- AVerdadeiro
- BFalso
8The acceleration of free fall for a body near the Earth is non-constant.
- AVerdadeiro
- BFalso
9The acceleration of free fall is about [blank_start]9.8 m/s^2[blank_end] or close to 10 m/s^2.
- A9.8 m/s^2
10All [blank_start]bodies[blank_end] falling [blank_start]freely[blank_end] under the force of [blank_start]gravity[blank_end] do so with [blank_start]uniform acceleration[blank_end] if [blank_start]air resistance[blank_end] is negligible.
- Agravity
- Buniform acceleration
- Cair resistance
- Dbodies
- Efreely
