The term for something that only has a magnitude
What is a scalar?
This term refers to the measurement the length that something has travelled
What is distance?
The unit of mass in physics
What is the kilogram?
You walk 20 meters West and then 10 meters East. What is the total distance.
What is 30 m?
The unit of force in physics
What is the Newton?
The term for something in physics that has magnitude and direction
What is a vector?
This term is the change in position of an object
What is displacement?
The units for velocity in physics
What is m/s?
You walk 20 meters West and then 10 meters East. What is your displacement?
What is 10 meters WEST?
This is how you calculate gravitational force or weight.
What is mass times the gravitational field strength?
Name two things in physics that are scalars which we have discussed in class so far
What is distance traveled, speed, and mass.
The term in physics describes an objects rate of change in position and its direction
What is velocity?
The units for acceleration in physics
What is m/s/s or m/s2?
An launched object needs to get the maximum range. What angle should it be launched at?
What is about 45 degrees?
What is the direction of the force that is always present on an object on Earth?
Where is straight downward from the object
This is a term that is used to describe the tendency for an object to stay at rest or stay in motion at constant velocity
What is inertia?
This term is the rate at which the velocity is changing
What is acceleration?
An object travels 500 meters in a straight line for 20 seconds. It's velocity is this value.
What is 25 m/s?
If there a a projectile fired at 40m/s at 40 degrees and we factor in air resistance, what is its vertical speed at its max height of 12 meters.
What is 0 m/s
What force would you use to measure how much you weigh on a scale
What is Force Normal
Name 3 things in physics that are vectors that we have discussed so far this year
What are displacement, velocity, acceleration, or force
This term refers to a projectile that is only under the influence of the force of gravity
What is free fall?
An object travels 4 miles east and 3 miles west. It takes 10 hours to do so. It's average velocity in miles per hour is this.
What is .1 miles per hour east?
An object travels 4 miles east and 3 miles north. It takes 10 hours to do so. It's average velocity in miles per hour is this.
What is .5 mph northeast?
What 2 equations do we use to connect forces and kinematics?
What is Fnet=sum of all forces and Fnet=ma
What is the exact name for the term that has units of N/kg
Gravitational field strength near Earth's Surface
This term refers to all the combined forces acting on an object
What is Net Force of Summation of Forces
An object travels 4 miles east and 3 miles west. It takes 10 hours to do so. It's average speed in miles per hour is this.
What is .7 mph?
An object travels 4 miles east and 3 miles north. It takes 10 hours to do so. It's average speed in miles per hour is this.
What is .7 mph?
