Chapter 5 Lesson 2

The rate at which the speed or the direction of motion of an object changes over time.

• acceleration

• inertia

• uniform motion

The tendency of an object to resist any change in motion.

• acceleration

• intertia

• uniform motion

True or False: Uniform motion is when the speed and direction change.

• true

• false

• true

• false

NGSS.3-PS2-1

Newton's first law of motion states

• that an object will stay in uniform motion unless a net force acts on the object.

• For every action there is an opposite or equal reaction.

• The more mass an object has the more force that is needed. F=MxA

Which object would have the least amount of inertia?

• 5 lb weight

• quarter

• volleyball

Newton's second law states

• The greater the mass of the object, the smaller its change in motion will be for a given force.

• An object will stay in uniform motion unless a net force acts upon that object.

• For every action there is an opposite or equal reaction.
