Measurement
Units for mass
What is a kg?
A vector that describes how fast something is going.
What is Velocity?
F = ma
What is Newton's 2nd Law?
The formula for Momentum.
What is p = mv?
Momentum before and after a collision is the same.
What is conservation of momentum?
Units for velocity
What is m/s?
The value that is 0 when you walk in a circle.
What is displacement?
Objects will not change velocity unless acted on by an outside force.
What is inertia/Newton's 1st Law
The impulse-momentum theorem.
What is the change in momentum = impulse?
A car collides with another and they drift off as a unit.
What is an inelastic collision?
The number of grams in a kilogram
What is 1000?
The slope of a velocity time graph.
What is acceleration?
Two forces that are equal and opposite, aka Newton's 3rd law.
The definition of momentum.
What is "mass in motion"?
A tennis ball and ball of clay are dropped to the floor. This object experiences an elastic collision.
What is a tennis ball?
Units for Momentum
What is kgm/s?
The name of the motion of thrown objects.
What is projectile motion?
The reason an object can have 0 net force on it, but be moving at constant speed.
What is ..acceleration being CHANGE in velocity?
No acceleration just means no increase/decrease in velocity.
Delta p
What is final momentum minus initial momentum?
A truck hits a motorcycle. This object experiences more force.
What is neither?
kg * m/s^2 is equal to this unit
What is a Newton?
Two balls. At the same time, one dropped down from a window, one thrown horizontally from the window. Which ball has the greater speed at ground level?
What is NEITHER!
They both experience the same acceleration due to gravity in the vertical direction.
The force that allows a car to make a turn on the road.
What is the force of friction?
The formula for impulse.
What is J = F times t?
Two objects of the same mass have the same kinetic energy. Object 1 experiences a elastic collision. Object 2 experiences an inelastic collision. This object LOST some kinetic energy.
What is Object 2?
