What is D?
200
This Force is due to the attraction of objects to the Earth.
What is the force of gravity (Fg)?
200
What is the weight of a 300 kg probe on the moon if acceleration due to gravity on the moon is 1.62 m/s^2
What is 486 N?
200
This information can be obtained from the slope of a displacement (position) vs time graph.
What is the velocity?
200
This is what the distances travelled by a projectile in the x direction and y direction are called.
What are distance (x) and height(y)?
300
This force is felt along the entire distance of an object when it is pulling an object against Fg.
What is a tension force (Ft)?
300
This law focuses on the fact that objects in equilibrium acts in equal and opposite forces (Fa on b = Fb on a).
What is Newton's 3rd law?
300
This information can be obtained from the slope of a velocity vs time graph.
What is acceleration?
300
What is the best angle to shoot a cannon from to get the maximum distance?
What is 45 degrees?
400
This force is a perpendicular force that is due to contact with an object.
What is the normal force (Fn)?
400
This Law focuses on the fact that the net force is the mass of an object times it's acceleration.
What is Newton's 2nd law?
400
