Physics
This term describes the resistance of an object to a change in its motion
What is Inertia?
An object at rest tends to stay at rest, an object in motion tends to stay in motion unless acted upon by an outside force.
What is Newton's First Law of Motion?
This is the net force.
What is the total force on an object.
Define acceleration.
What is the change in velocity?
This is the largest planet in our solar system.
What is Jupiter?
This is the unit of mass
What is a kilogram?
What is F=ma?
The effect of balanced and unbalanced forces on an object's motion
Balanced forces - no motion.
Unbalanced - motion.
[Must answer both parts of the question]
Describe the difference between speed and velocity.
Speed is scalar, velocity is a vector.
This playwright is known for writing "Romeo and Juliet."
Who is William Shakespeare?
This is the unit of force
What is a Newton?
Solve: What is the mass of an object that accelerates at a rate of 5 m/s/s when 60 N is applied to it.
12 kg
Calculate the net force acting on an object with a mass of 10 kg that is accelerating at 2 m/s².
F=ma. F=(10)(2) = 20 N
What is 20 N?
The change in velocity over time.
What is acceleration?
This city is the capital of Australia.
What is Canberra?
Describe the relationship between mass and acceleration when a constant force is applied.
As mass increases, the acceleration decreases.
Provide a real-world example of Newton’s Second Law in action.
[Teacher discretion]. Must include force, mass, and acceleration.
Calculate the mass of an object with a force of 250 N that is accelerating at 2 m/s².
What is 125 kg
Describe what the slope of a position-time graph represents.
What is velocity?
This is the chemical symbol for gold.
What is Au?
Describe what happens to the acceleration of an object if the mass is doubled while the force remains constant?
The acceleration decreases by half.
Describe how mass affects acceleration according to Newton's Second Law.
As mass increases, the acceleration decreases, and the opposite.
Solve: a 5 kg object experiences a force of 20 N, what is its acceleration?
a = F/m, a = 20/5 = 4 m/s/s
What is 4 m/s/s?
A car accelerates from 0 to 60 m/s in 10 seconds, what is its average acceleration?
6 m/s/s
This year marks the sinking of the Titanic.
What is 1912?
