Newton's 1ST Law of Motion
The tendency of an object to resist a change in its state of motion, requiring an unbalanced force to alter its speed or direction.
What is inertia?
This is the mathematical equation that summarizes Newton's Second Law, relating force, mass, and acceleration.
What is F = m × a (Force equals mass times acceleration).
For every action force, there is a force of this kind that is equal in magnitude and opposite in direction.
What is a reaction force?
Any substance that measures below 7 on the pH scale is classified as this type of compound.
What is an acid?
This property allows water molecules to stick to each other, creating surface tension and causing drops to be spherical.
What is cohesion?
The law states that an object at rest will stay at rest, and an object in motion will stay in motion with a constant velocity, unless acted upon by this.
What is an unbalanced force?
This describes the relationship between net force and acceleration; if one doubles, the other also doubles.
What is More force means more acceleration?
A swimmer pushing water backward and the water pushing the swimmer forward is a perfect illustration of this specific law.
What is Newton’s Third Law of Motion?
This is the texture that many bases or alkaline solutions, like soap, feel like to the touch.
What is slippery?
This property allows water to stick to other surfaces, which, combined with cohesion, helps water travel up plant stems.
What is adhesion?
When a car suddenly stops, your body continues to move forward due to this law, making a seatbelt an essential safety device.
What is Newton’s First Law of Motion?
This describes the relationship between an object's mass and its acceleration; if one doubles, the other is halved.
What is More mass means less acceleration?
If a softball hits a bat with 500 N of force, the bat exerts this much force back on the softball.
What is 500 N, but in the opposite direction?
This type of test paper is often used to quickly determine if a substance is an acid (turns red) or a base (turns blue).
What is litmus paper?
This is the specific term for the skin-like film on the surface of water, caused by cohesion, that allows water strider insects to walk on the water.
What is surface tension?
An object moving at a constant speed in a straight line is said to be in this state, meaning the net force acting on it is zero.
What is equilibrium (or balanced forces)?
This is the unit for force, defined as the force required to accelerate a 1-kilogram mass at a rate of 1 meter per second squared.
What is newton (N)?
The force that a rocket uses to move upward is the reaction to the very strong force of hot gas being pushed in this direction.
What is Downward?
The chemical reaction that occurs when an acid and a base are mixed together, resulting in a pH closer to 7.
What is neutralization?
Water is the only common substance on Earth that naturally exists in all three of these states at typical surface temperatures.
What is solid, liquid, and gas?
The amount of this property determines an object's inertia; a larger amount means a greater resistance to a change in motion.
What is Mass?
A baseball has a mass of 0.15 kg. If it is hit with a net force of 30 N, this is the resulting acceleration in m/s2
What is 200 m/s²?
This force pushes the boat backward when you jump off it into the water.
What is the reaction force?
Stomach acid, lemon juice, and vinegar are common household substances that all share this characteristic pH property.
What is they are acidic?
A single molecule of water is made up of two atoms of Hydrogen and one atom of this element.
What is Oxygen?
