True or False: Vectors are drawn from head to tail.
What is True.
100
The speed of an object with direction.
What is Velocity.
100
Define Scalar & Vector. (List 1 example of each)
- Scalar: Quantity with only magnitude (time, speed, or distance)
- Vector: Quantity with magnitude and direction (velocity or acceleration)
200
Define Friction.
What is A Force that Opposes Motion.
200
What happens to the horizontal velocity (vₓ) as an object falls?
What is Remains Constant.
200
The rate in which the velocity of an object changes over time.
What is acceleration.
200
Objects released which are only affected by gravity.
What are Projectiles.
300
Name the 4 kinds of forces.
What is Gravitational, Electromagnetic, Strong Nuclear, & Weak Nuclear.
300
_____________ can be used to find the resultant force vector of two forces acting on an object.
What is the Pythagorean Theorem.
300
What does the area under the slope of a Velocity vs. Time graph represents.
What is Displacement.
300
Slope represents this on a time graph.
What is Acceleration.
400
Explain the relationship between mass and weight.
Mass is constant throughout the universe, while weight changes with the force of gravity. Mass is the amount of matter in an object while wight is a force of gravity acting on a mass.
400
The greatest range is achieved when a projectile is launched at a ____ degree angle.
What is 45.
400
What does the slope of a Displacement vs. Time graph represent?
What is Velocity.
400
Without ___________, all objects would fall at 9.8m/s²
What is Air Resistance.
500
What 3 factors do Force of Friction depend on?
What is 1) Nature of two Forces
2) Smoothness of the Surface
3) Normal Force Pressing Surfaces Together
500
Vertical motion for a projectile increases or decreases because of acceleration due to ___________.
What is Gravity.
500
True or False: A heavier object falls faster than a lighter object. (Ignoring air resistance)
What is True.
500
List Newtons 3 Laws of Motion
1) an object at rest stays at rest or moves at constant velocity unless acted upon by a net force (inertia)
2) a net force acting on a mass causes it to accelerate (F=ma)
3) an object exerting a force on a second object experiences the equal but opposite force from the second object (action-reaction)
