The aircraft pushes the gases backwards but the gases push the aircraft forward just as hard

This is true and follows from Newton's 3rd Law

Acceleration means . . .

Change in speed divided by time

The aircraft is climbing. This means that . . .

The uplift must be greater than its weight

Newton's Second Law states that the aircraft shown in the picture

Has a thrust equal to its mass times its acceleration

Newton's First Law states that the aircraft shown in the picture

Red answer is true but only with no unbalanced force acting

Answers

1
In the picture of the tank on the bridge, identify the force which has been labelled F1
Lift / reaction force
Weight/ Gravity
Friction / drag
Thrust / Engine
2
The aircraft pushes the gases backwards but the gases push the aircraft forward just as hard
This is true and follows from Newton's 1st Law
This is false
This is true and follows from Newton's 3rd Law
This is true and follows from Newton's 2nd Law
3
Acceleration means . . .
Change in distance divided by time
Change in displacement divided by time
Change in speed divided by time
None of these
4
In the picture of the tank on the bridge, identify the force which has been labelled F3
Weight/ Gravity
Thrust / Engine
Friction / drag
Lift / reaction force
5
Gravity is a type of
Force
Weight
Energy
Speed
6
The aircraft is climbing. This means that . . .
The force of the engines is less than the drag
None of these are true
The uplift must be greater than its weight
The force of the engines is greater than its weight
7
Newton's Second Law states that the aircraft shown in the picture
Keeps moving at the same direction & same speed
Answer 1 is true but only if an unbalanced force acts on it
Has a thrust equal to its mass times its acceleration
Answer 1 is true but only if no unbalanced force acts on it
8
The aircraft is accelerating. This means that . . .
The force of the engines is less than the drag
The uplift must be greater than its weight
The force of the engines is greater than its weight
None of these are true
9
In the picture of the tank on the bridge, identify the force which has been labelled F2
Lift / reaction force
Thrust / Engine
Weight/ Gravity
Friction / drag
10
Newton's First Law states that the aircraft shown in the picture
Keeps moving at the same direction & same speed
Red answer is true but only with an unbalanced force acting
Has a thrust equal to its mass times its acceleration
Red answer is true but only with no unbalanced force acting
