Newton's First Law is also known as the Law of ... ?
Mass
Inertia
Newtons
Friction
What does it mean when we say a force is "unbalanced" in the context of Newton's First Law of Motion?
The force does not change the object's direction of motion.
The force causes the object to move at a constant velocity.
The force causes a change in the object's state of motion.
The force is equal in magnitude and opposite in direction to another force acting on the object.
If you push a shopping cart with a certain force and it accelerates at 2 m/s², what would be the cart's acceleration if you push it with double the force, assuming the mass remains constant?
1 m/s²
2 m/s²
4 m/s²
8 m/s²
Newton's Second Law states that the force acting on an object is equal to the mass of the object multiplied by its acceleration. Which formula represents this law?
F=m/a
F=ma
F=a/m
F=m+a
The formula that we use in Newton's Second law is ... ?
F = A/M
F = M + A
F = MA
S = DV

Inertia
According to Newton's Second Law, if the mass increases the _______ must also increase to move the object.
Mass
Force
Inertia
Acceleration
What is net force?
The force being applied to the left.
The total of all forces acting upon an object.
A push or pull.
When forces are applied in different directions, which way will the object move?
In the direction of the smaller force.
The object won't move.
In the direction of the larger force.
To the side with the most mass.

The brick has a mass of 10kg. The balloon has a mass of 1kg. Which object has more inertia? // El ladrillo tiene una masa de 10 kg. El globo tiene una masa de 1 kg. ¿Qué objeto tiene más inercia?
The brick // El ladrillo
The balloon // El globo
They both have the same amount of inertia // Ambos tienen la misma cantidad de inercia
How do you know if an object has a balanced force?
It's stationary or moving at a constant speed.
A force causes a change in it's position.
It's speed increases.
Newton's First Law and Second Law
A) An object at rest will remain at rest unless acted upon by an unbalanced force.
B) An object in motion will continue in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
C) The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
D) Both A and B are correct.
