Force & Motion
An unbalanced force doesn't affect motion.
What is False
Define Newton’s First Law
An object in motion stays in motion and an object at rest stays at rest unless acted on by an outside force
What is the definition of Newton’s Second Law
Force is equal to the change in momentum over the change in time or Force = mass * acceleration
Define Newton’s Third Law
Every Action has an equal and opposite reaction
Resistance to change
Inertia
A____ is a push or pull. A.rubber chicken B.force C.inertia D.Guatamala Bay
What is Force
The property of matter Newton discovered for his first law
Inertia
How do you calculate acceleration
Change in Velocity Acceleration = --------------------Change in Time
In Newton’s third law, equal means…
Equal in size and time
The result of unbalanced forces
Change in Motion Acceleration Net Force
What is the definition for inertia? Give similar answer.
What is The tendency of matter to resist a change in it's state of motion.
How is an objects inertia measured?
By calculating the mass of the object
If Force = Mass*Acceleration what is inversely proportional to acceleration and give an example of what it means
Mass: when mass increases acceleration decreases and when mass decreases acceleration increases
In Newton’s third law, opposite means…
At 180 degree angles or in the complete opposite direction
The rate at which velocity changes with time
Acceleration
What is a balanced force? Give the closest answer possible.
What is Equal forces that act in opposite directions on an object and cancel one another out.
Two ways you can overcome an objects inertia
Make the object move or stop moving change the objects direction
If Force = Mass*Acceleration what is directly proportional to acceleration and explain what directly proportional means
Force: if you increase your force, acceleration increases if you decrease your force, acceleration decreases
In a collision, are the forces equal on both of the object in the collision, why
The forces are equal because each object has their own force reflected back on them and the other objects force is added to it
Measure of gravitational attraction
Weight
______is a force that does not cancel one another out. A.balanced force. B.unbalanced force C.giraffe D. acceleration
What is Unbalanced
If a Semi Truck hit a Toyota Prius which object would travel farther and why
The Toyota Prius because it has less mass and therefore less inertia
If a 2000 kg car goes from 0 m/s to 10 m/s in 5 seconds, what is its force?
4000 Newtons
If objects in a collision have equal forces acting on them will the objects always travel the same distance, why or why not?
The objects will only travel the same distance if their masses and therefore inertia are equal. If they are not, the object with less inertia will travel farther.
Used to calculate acceleration similar to speed but with an additional requirement
Velocity
