Forces & Momentum quiz Flashcards
What is Newton’s first law?
An object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force
Formula for force:
Mass x Acceleration
What is the law of the conservation of momentum?
Momentum is neither created nor destroyed but only changed through forces acting on an object
Formula for average acceleration:
(Final Velocity - Initial Velocity) / time
What is Newton’s first law also known as?
Law of Inertia
What is Newton’s third law?
For every action, there is an equal and opposite reaction
Is momentum a vector or scalor?
Vector
Formula for acceleration:
Force / Mass
What is an example of Newton’s third law?
Diver jumping on a jumping board and it pushing back
Formula for momentum:
Mass x Velocity
Is kinetic energy a vector or scalor?
Scalor
Formula for mass:
Force / Acceleration
T or F: Is some momentum transferred when an object collides with another?
True
Formula for speed:
Distance / time
How is momentum measured?
Kilograms x m/s
