Early lessons : 1D motions and Graphing
Whats the order of Design Making
What is Empatnize,Define,Porto Type,Test,and Identify
Formula for Weight
Mass x G (9.8)
What is G?
what is friction?
Friction: is a force that opposes motion between 2 surfaces.
What is a Vector?
Vector: has a magnitude (size) and direction.
what is constant speed
What is force
An action that can change motions.
What is mass measured in and weight measured in?
Mass: Kg
weight: N
What is friction equation?
Friction force= Coefficient of friction x Weight (normal force)
What is a free body-diagram?
A drawing of a part of a complete system, isolated in order to determine the forces acting on that rigid body.
What is the formula for V
V= vo+at
What is inertia
A term used to measure the ability of an object to resist a change in its state of motion.
What is the diffrence between mass and weight?
Mass: the amount of matter in an object.
Weight: is the force of gravity on the objects mass.
What is density?
Density: the amount of mass in a volume.
What is the equation of Force in a Spring?
-Kx
What is Displacement
A car is moving at 5m/s , How much acceleration do you need for it to stop in 3 seconds . How far does it go in the time? . If the car is 5000 kg how much is need to stop the car.
Distance=7.35
Stop = 49980.3
A car accelerates from 10 m/s to 20 m/s in 2s . If the mass is 1000kg , what is the force on it.
5000N
what is the difference between static fritcion and kinetic friction?
Static: when the object is not moving
kinetic: when the object is moving
How much force is needed to stretch a spring by .2m if it has a spring constant of 100N/M?
Spring by force = -20
How is acceleration shown in a Dt graph
Curved
What is Newtons First Law?
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted up on by an unbalanced force
What is Newtons 3rd law.
what is Hooke's Law equation?
N=-(N/M)(M)
