Homework - Newton's 2nd and 3rd law

#### Slide 2 -Slide

What is the relationship between force, mass, and acceleration?
A
Force = mass x acceleration
B
Force = mass / acceleration
C
Force = mass + acceleration
D
Force = mass - acceleration

#### Slide 3 -Quiz

What happens to an object's acceleration if a larger force is applied?
A
It remains constant
B
It decreases
C
It increases
D
It becomes zero

#### Slide 4 -Quiz

How does the mass of an object affect its acceleration?
A
The mass and acceleration are unrelated
B
The larger the mass, the smaller the acceleration
C
The mass has no effect on acceleration
D
The larger the mass, the larger the acceleration

#### Slide 5 -Quiz

What does acceleration represent?
A
A change in position
B
A change in force
C
A constant speed
D
A change in velocity

#### Slide 6 -Quiz

In the formula F = ma, what does 'F' represent?
A
Energy
B
Mass
C
Acceleration
D
Force

#### Slide 7 -Quiz

What does a larger mass of an object require to change its velocity?
A
A larger force
B
No force
C
A smaller force
D
The same force

#### Slide 8 -Quiz

What happens to an object's acceleration when a larger force is applied?
A
It decreases
B
It turns into mass
C
It increases
D
It remains constant

#### Slide 10 -Slide

What is the statement of Newton’s third law?
A
For every force there is an equal and opposite force
B
For every action there is an equal and opposite reaction
C
For every motion there is an equal and opposite motion
D
For every reaction there is an equal and opposite action

#### Slide 11 -Quiz

According to Newton’s third law, what happens when two objects interact?
A
The forces cancel each other out
B
A pair of forces act on the two objects
C
No force is exerted on the objects
D
A single force acts on both objects

#### Slide 12 -Quiz

Why does a rocket move upward when the hot gases are expelled downwards?
A
Due to gravity pulling the rocket upward
B
Due to the equal and opposite reaction forces
C
Due to the rocket's shape and design
D
Due to the rocket's mass

#### Slide 13 -Quiz

Why do you move forward when you walk even though your feet push backwards?
A
Your body's momentum carries you forward
B
Friction between your feet and the ground
C
Your feet propel you forward
D
The ground exerts an equal and opposite force forward

#### Slide 14 -Quiz

What is the relationship between the size and direction of the forces in Newton’s third law?
A
The size of the forces on one object is greater than the other
B
The size of the forces on each object is equal and the direction is opposite
C
The size of the forces on each object is different and the direction is the same
D
The direction of the forces on each object is the same

#### Slide 15 -Quiz

A
Friction slows down the body
B
Air resistance pushes the body back
C
Inertia keeps the body moving forward
D
Gravity pulls the body forward

#### Slide 19 -Quiz

Why does a moving object continue to move at a constant speed when no force is acting on it?
A
Inertia
B
Momentum
C
Friction
D
