This step of the scientific method is when an educated prediction is made.
WHAT IS HYPOTHESIS
Gwen flies forward when her bike stops suddenly because of this law.
What is Newton's First Law of Motion?
The force responsible for keeping planets in orbit around the Sun.
WHAT IS GRAVITY?
This piece of equipment measures mass.
What is a digital scale?
Scientists use models mainly for this purpose.
What is to explain ideas and phenomena?
Scientists perform multiple trials for this reason.
WHAT IS TO DETERMINE IF RESULTS CAN BE REPRODUCED?
A bus with an acceleration of 0 m/s² is moving at this type of speed.
What is constant speed?
As distance between two objects increases, gravitational force does this.
What is decreases?
The formula used to calculate speed.
What is distance ÷ time?
A rubber band model of gravity is useful because it does this.
What is helps explain forces between objects?
Before beginning an investigation about bicycle oxidation, Freddy should do this first.
WHAT IS RESEARCH PREVIOUS STUDIES?
The formula that relates force, mass, and acceleration.
What is F = ma?
Two bowling balls exert the greatest gravitational force when separated by 1 METER OR 2 METERS?
What is 1 meter?
A car travels 24 meters in the last 3 seconds of a trip. Its speed is this.
what is 8 m/s?
Scientific models help explain scientific laws by doing this.
What is illustrating situations where the law applies?
Avogadro demonstrated that the masses of different samples corresponds to the molecular weight of the gas. Why does his investigation qualify as science? (What was he doing?... NOT experiment).
WHAT IS TESTING A HYPOTHESIS?
A 10-kg wagon pulled with a force of 20 N accelerates at this rate.
What is 2 m/s²?
If the distance between two objects doubles, a 100 N gravitational force becomes this.
What is 25 N?
On a speed-time graph, if speed remains above zero, this is happening to total distance traveled.
What is increasing?
A cement truck carrying a full load causes more damage because it has this.
What is greater mass?
When testing detergents, all cloth samples should be this to ensure a fair test.
WHAT ARE IDENTICAL PIECES OF CLOTH?
To calculate the force in a car crash using Newton's Second Law, these two variables are needed.
What are mass and acceleration?
An astronaut with a mass of 60 kg weighs this much on the Moon (g = 1.6 N/kg).
What is 96 N?
This quantity changes whenever an object speeds up, slows down, or changes direction.
What is velocity?
A car slows from 50 km/h to 30 km/h. The acceleration is this type.
What is negative acceleration (deceleration)?
