Forces
This is the simple scientific definition of a force.
What is a push or a pull?
Newton’s First Law is also known as the law of this.
You calculate this basic metric by dividing total distance by total time.
What is average speed?
This universal attractive force pulls any two masses toward each other.
What is gravity?
This is the metric unit used to measure the strength of a force.
What is a Newton (N)?
This is the term for the sum of all forces acting on an object.
What is the net force?
this tendency of matter to resist any change in its motion depends directly on an object's mass.
What is inertia?
This is speed combined with a specific direction (for example, 30 mi/hr West).
What is velocity?
This is the amount of matter inside an object, which stays the same no matter where it goes in the universe.
What is mass?
This basic formula is used to calculate the speed of a moving object.
What is Distance divided by Time (\(S=d/t\))?
Clue: These types of forces cancel each other out and do not change an object's motion.
What are balanced forces?
This formula mathematically represents Newton’s Second Law (F = ma).
What is Force = Mass × Acceleration?
This is defined as any rate of change in velocity over time—including speeding up, slowing down, or turning.
What is acceleration?
This measurement is actually the downward pull of gravity acting on an object's mass.
What is weight?
On a standard Distance-Time graph, a completely flat, horizontal line indicates that the object is doing this.
What is standing still?
This type of force causes an object to speed up, slow down, or change direction.
This law states that for every action, there is an equal and opposite reaction.
What is Newton’s Third Law?
Even if a satellite or the moon orbits Earth at a steady speed, it is still accelerating because of this change.
What is changing direction?
On the Moon, your mass stays the same, but this value decreases because the Moon has less gravity than Earth.
What is your weight?
This is the metric unit for acceleration
meters per second squared
This contact force acts in the opposite direction of motion when two surfaces rub together.
If you push a heavy textbook and a light pencil with the exact same amount of force, this object will have a greater acceleration.
What is the pencil?
What is acceleration?
This fluid friction acts on a skydiver or a paper airplane moving through the air.
What is air resistance?
This is the metric unit for mass
