Energy & Force
The force that opposes motion between two surfaces.
Friction
A car travels 120 miles in 2 hours. Find its speed.
60 MPH
Who was Isaac Newton & how many laws of motion did he come up with?
English Scientist and Mathematician who had a profound impact on describing physical laws; 3.
The energy of the projectile moving through the air.
Kinetic Energy
G-Men & Lady G-Men
Describe potential & kinetic energy.
Potential=stored, Kinetic=motion
A car traveling 65 mph north is an example of this measurement
Velocity (speed + direction)
For every action...
there is an equal and opposite reaction.
Mass and weight are the same thing. True or False?
False
Which streaming service has the most subscribers: Disney+, Netflix, or Amazon Prime?
Netflix (300m+ users)
The type of force needed to change motion; an object at rest stays at rest unless acted upon by this.
Unbalanced Force
On a distance-time graph, this is usually shown on the x-axis.
Time
What is the equation for mass?
Force / Acceleration
The catapult arm pushing the projectile while the projectile pushes back on the arm demonstrates this law.
Newton's 3rd Law
Cleveland Cavaliers, Miami Heat, LA Lakers, Philadelphia 76ers
The type of potential energy that relates to an object's shape is changed; stretched or compressed.
Elastic Potential Energy
A horizontal line on a distance-time graph means this.
The object is not moving.
This law explains why pushing a lighter shopping cart is easier than pushing a heavier one
Newton's 2nd Law
What were the three main factors that most affected your catapult launch, as based on Newton's 2nd Law?
Force, Mass, Acceleration
How many siblings does Mr. Pertuset have?
5
The straight-line change in position from start to finish
Displacement
On a speed-time graph, a line moving upward indicates this.
The object is accelerating
Newton's First Law is also known by this name.
The Law of Inertia
What were the independent and dependent variables during your catapult launch?
Independent: design build, amount of rubber bands, launch strategy (the things you could change)
Dependent: speed, velocity, energy (the things you could measure)
What year was KFC founded?
1930
