Class Resources 1st Quarter
Watch the entire MagLev video (look in powerpoint below) and use the diagrams in the powerpoint to answer the questions.
BELLWORK WEEK OF 9/6:
Tuesday: Choose a question from the list we made at the beginning of the unit and explain why we can now answer it. (look in classroom for questions)
Wednesday:
- What is the difference between speed and velocity?
- Define acceleration. What does it mean besides an increase in speed?
- An object, such as a planet, circling another object, such as the Sun, at a constant speed is said to be accelerating. Explain why this motion is an example of acceleration.
Thursday:
For each, explain if it's more Newton's 1st, 2nd or 3rd Law and why.
1. A ball sits on the ground. Later, a child kicks it.
2. A swimmer pushes on the water and the water pushes back, propelling themforward.
3. A car and truck both accelerate at the same time. The truck takes longer to move.
Vocabulary List First and Second Laws Stations:
Acceleration: a change in speed or direction; includes speeding up, slowing down, and changing direction
Mass: The amount of matter in an object
Velocity: the speed and direction of an object
Newton: the unit we use to measure force strength
Newton's 1st Law of Motion: inertia; an object at rest or in motion will remain at rest or in motion until an unbalanced force acts upon it.
Newton's 2nd Law of Motion: F=m x a; the amount of force needed to cause an object to accelerate (change speed or direction) depends on it's mass.
