Newton's Laws of motion
The reason a chair slows down after you push it across the floor is due to this type of force.
What is frictional force?
This is one form of the equation that represents Newton's Second Law of Motion.
What is F=ma, a=F/m, or m=F/a.
This type of force is what's responsible for getting an object moving.
What is the Force Applied?
What is the amount of matter in an object?
What is Mass
This is the natural tendency of objects to keep on doing what they're doing.
What is Inertia
An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
What is Newton's First Law of Motion
You left your book on a desk in Mr. Lopez's room and it is still there the next morning. This is an example of which law of motion?
What is Newton's First Law.
This is the type of force that opposes gravity when the object is at rest on a surface.
What is the Normal Force?
This law states that the mass of an object is inversely proportional to the acceleration that is undergoes.
What is Newton's Second Law of Motion?
This is a push or pull.
What is Force
A kickball continues to roll until it hits the fence. This is an example of which law of motion?
What is Newton's First Law.
You are thrown off the front of a 4 wheeler when it runs into a fence. This is an example of which law of motion?
What is Newton's First Law.
True or False: If an object is pushed with more force, it will move faster, or have a greater acceleration.
What is true?
What is the measure of gravitational attraction or force/amount of mass?
What is Weight
What are the four elementary types of forces?
Strong nuclear, weak nuclear, electromagnetic, gravity
A car is easier to push than a bus. This is an example of which of Newton's Laws?
What is Newton's 2nd law.
The baseball went farther than the basketball when your classmate hit them with an aluminum bat. This is an example of which law of motion?
What is Newton's Second Law of Motion.
What will happen to an object at rest when balanced forces act on it
It will remain at rest
What is the mass of a person who has a force of 500 N pulling on them on a planet whose gravity is 11.5 m/s^2?
What is 43 kg?
This is the weight (NUMBER AND UNIT) of a person whose mass is 55 kg and is standing on planet Earth.
What is 539N ?
This is the force that you must overcome to start an object moving.
Static friction
A soccer ball kicked with a force of 13.5 N accelerates at 6.5 m/s^2 to the right. What is the mass of the ball?
m = 2.1 kg
A 2.0 kg otter starts from rest at the top of a muddy incline 85 cm long and slides down to the bottom in 0.50 s. What net force acts on the otter along the incline?
14 N
A 27 N net force acts on a 9 kg rock. What is the acceleration of the rock?
3 m/s^2
This is the force that you must overcome to start an object moving.
