EFFECT OF INERTIA IN DAILY LIFE

Inertia is

• product of the mass of a particle and its velocity

• for every action (force) in nature there is an equal and opposite reaction.

• the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.

• tendency of an object to remain at rest or, if moving, to continue its motion in a straight line at uniform velocity.

Newton’s First Law states that

• the acceleration of an object is directly related to the net force and inversely related to its mass. Acceleration of an object depends on two things, force and mass.

• an object will remain at rest or move at uniform velocity unless acted upon by an external force.

• for every action (force) in nature there is an equal and opposite reaction.

• product of the mass of a particle and its velocity.

The larger the mass of an object, the _____________ the inertia of the object

• larger

• smaller

• same

The inertial balance can be used to _________________.

• measure weight

• measure mass.

• measure size

• measure height

• share your seat

What is Newton's First Law known as? The Law of

• Friction
• Mass
• Inertia
• Gravity

The law of inertia (Newton’s First Law) applies

• to both moving and nonmoving objects
• only to moving objects
• only to objects that are not moving

Why does an 18-wheeler truck have more inertia than a bicycle?

• it has more mass

• it has more volume

• it is not as aerodynamic

• It has more space

Which has a greater inertia?
