Force & Acceleration
The formula for calculating acceleration?
What is A=F/M?
What does Newton's First Law of Motion state?
What is an object at rest stays at rest unless acted upon by a net force?
In the formula F = ma, the “a” stands for this.
What is acceleration?
What force is primarily responsible for keeping a satellite in orbit?
What is gravitational force?
Who is known as the father of modern physics?
Who is Isaac Newton?
If a net force of 10 N acts on a 2 kg object, what is its acceleration
What is 5 m/s²?
In a car crash, why do seat belts help protect passengers?
What is they counteract inertia (Newton's First Law)?
If the mass of an object increases while the force stays the same, the acceleration does this.
What is decreases (slows down)?
How do seat belts in cars relate to Newton's laws?
What is they prevent sudden acceleration in a crash (First Law)?
Newton’s First Law is why you need to wear this when riding a bike, in case you suddenly stop.
What is a helmet?
How does increasing the mass of an object affect its acceleration when the net force is constant?
What is acceleration decreases?
How does Newton's Second Law apply to a soccer ball being kicked?
What is the acceleration depends on the force of the kick and the mass of the ball?
This word describes the sum of all forces acting on an object.
What is net force?
Why do heavy objects require more force to move than lighter ones?
What is because they have more mass (Second Law)?
What does the law of inertia relate to?
Newton's 1st law. Resisting a change in motion
What is the unit of force
What is the Newton (N)?
What is a real-life example of Newton's Third Law of Motion?
What is when a rocket launches, the engines push down on the ground, and the rocket moves up?
Explain why a bowling ball accelerates less than a soccer ball when the same force is applied.
What is because the bowling ball has more mass, so acceleration is smaller?
How do amusement park rides demonstrate the concepts of acceleration?
What is they use forces to speed up and slow down the ride?
Isaac Newton is also famous for studying this natural force that makes apples fall from trees.
What is gravity?
If an object has a mass of 3 kg and experiences an acceleration of 4 m/s², what net force is acting on it
What is 12 N?
Explain how a roller coaster demonstrates all three of Newton's laws of motion.
What is it shows inertia (First), acceleration due to forces (Second), and action-reaction pairs (Third)?
If no net force acts on an object, its acceleration is…
What is zero?
In bumper cars, when one car hits another, the forces on each car are equal but opposite. This demonstrates Newton’s ___ Law.
What is the Third Law?
What common phrase summarizes Newton's Third Law?
What is "for every action, there is an equal and opposite reaction?"
