Physics Class Notes
Electricity Comes From Atoms
Atoms have positive and negative charges in them.
The protons in the nucleus create the positive charge.
The electrons create the negative charge.
A neutral atom has an e
1. The 32,500 kg school jet is on the Orlando Executive runway. What net (unbalanced)
force is necessary to accelerate the jet to its takeoff acceleration of 1.20 m/s2?
Acceleration- 1.20 m/s2
Net Force- N
n= 39000 net
Consider hitting a baseball with a bat. Which scenario is true?
The baseball exerts a greater force on the bat than the bat exerts on the baseball.
The bat exerts a greater force on the baseball than the baseball exerts on the bat.

Initial Speed Lab
Purpose; To determine the distance traveled of a baseball at different initial speeds
Introduction; Today we are going to test the different distances a baseball will travel
when the initial speed is altered.
1. The shape of the graph is a half parabola (non linear) because it is curving upwards with
a positive slope and getting large and larger. The grap
1. What is the momentum of a person of 90 kilograms running at 5 meters per second?
2. What is the momentum of a car weighing 1,500 lbs that is traveling at 40 MPH?
1. Define gravity.
Gravity is an attractive force that acts on any two objects with mass
2. What is the difference between mass and weight?
Mass is the amount of matter in an object.
Weight is a measure of gravitational attraction to an object.
1. What is the acceleration on the Earth? Show the calculations.
The equation for acceleration is d = 1/2at^2
Distance = 3.5m and Time = .84s
Need to find acceleration, a=(2d)/t^2
a= (2(3.5)/.84^2 a= 9.92m/s
2. What is the acceleration on the moon?
a. The Large Hadron Collider accelerates particles.
b. The Large Hadron Collider is made up of two beams of particles that circle
around a ring in opposite directions, they travel close to the speed of light and try
