Newton's Laws
This law is simply stated as "Net force = mass x acceleration".
What is Newton's second law of motion?
The force that accelerates objects to the center of the earth.
What is gravity?
The amount of matter in an object
What is mass?
This is what FBD stands for.
What is a free body diagram.
This is the unit of Force.
What is a Newton?
This law states that if one object exerts a force on a second object, the second object exerts an equal, but opposite force on the first.
What is Newton's third law of motion.
This force acts along a flexible connection, parallel to the flexible connection.
What is tension?
The force an object experiences due to its acceleration from gravity.
What is weight?
Draw the FBD that shows an object, at rest, on a table.
Mrs. Kinney will hold up the FBD.
This is Mrs. Kinney's favorite way to drink coffee.
What is black.
These are the words missing below: A body at rest tends to remain at rest. A body in motion, tends to remain in motion, at a ____________ ___________ unless acted on by a net external force.
What is "constant velocity"?
This support force acts perpendicular to the surface.
What is the Normal force?
The sum of forces acting on a system.
What is the net force, or net external force.
Draw a FBD of an apple in free fall. (Neglect air resistance.)
Check against Mrs. Kinney's.
An car, starting at rest, begins to accelerate with a constant acceleration of 0.5 m/s2. After traveling a distance of 25m, this is the car's final velocity.
What is 5m/s?
This quantity is directly proportional to the net external force on a system.
What is acceleration?
This applied force is the result of combustion gasses.
What is thrust?
The average position of all the parts of a system or object.
What is the center of mass?
Draw a FBD that shows a man/bike system hitting a box on the road.
This is what Mrs. Kinney taught before she came to RHS.
What is "baby physics", middle school, or 8th grade science.
This is the word missing below:
If a force of 10N is applied to two objects, the object with more mass will experience a _____ acceleration.
What is smaller?
This is a force that opposes motion along a surface.
What is friction?
The tendency of an object at rest to remain at rest; or the tendency of an object in motion to remain in motion.
What is inertia/the law of inertia?
Draw a FBD for a 100g weight hanging (at rest) from a string. Consider the weight as the only component of the system.
See Mrs. Kinney's drawing.
A rock is thrown down from the top of a building with an inital velocity of 20 m/s. The rock hits the ground with a final velocity of 40 m/s. This is the height of the building.
What is 60m tall?
