Newton's Second Law

If a car driving through a school zone, and then gets on a freeway. Describe the speed and acceleration

• low speed, high acceleration

• low speed, low acceleration

• high speed, high acceleration

• high speed, low acceleration

I the mass of an object is 10 kg. And the acceleration is 10 m/s², what is the force on the object?

• 1000 N

• 20 N

• 10 N

• 100 N

(a)   = mass x acceleration

A (a)   is required to change the motion of an object

Which of these is not an example of acceleration

• Change in motion

• Change in velocity

• Change in direction

• Change in color

Newton's 2nd law states a decrease in mass of an object will cause the the acceleration to _____ only if _______

• increase, the force is constant

• decrease, the force is constant

• increase, the mass is constant

• decrease, the mass is constant

Newton's 2nd Law states an increase in mass of an object will cause the acceleration to (a)   only if the force is constant

Newton's 2nd Law states an increase in net force on an object will cause the acceleration to INCREASE only if the (a)   is constant.

Newton's 2nd Law states that a decrease in net force on an object will cause the acceleration to ______ only if the ______

• decrease, net force is constant

• decrease, mass is constant

• increase, mass is constant

• increase, net force is constant

Which of these is NOT one of the galaxies in the phenomena video?

• Triangulum

• Alpha Centari

• Milky Way

• Andromeda
