Inertia

What is inertia ?

• Inertia is the energy stored in an object at rest.
• Inertia is the force that causes an object to move faster.
• Inertia is the speed of an object in motion.
• Inertia is the resistance of an object to changes in its motion.

Velocity is the combination of ------

• speed and distance
• acceleration and direction
• speed and motion

• speed and time

What is the law of Inertia ? simply answered

• Objects in motion will eventually stop without any force.
• Inertia only applies to objects at rest, not in motion.
• The law of inertia states that all objects will move at the same speed.
• The law of inertia is the principle that objects that are in motion stay in motion.

Inertia is resistance to changes in it's

• velocity
• speed
• motion
• direction

• Yes

• No

Less mass means

• No change in acceleration and weight.
• Decreased acceleration and higher weight.
• Increased mass and lower speed.
• Increased acceleration and lower weight.

What is the reason we need seatbelts as it relates to inertia ?

• Seatbelts are only required for children under 12.
• Seatbelts are designed to enhance comfort during long drives.
• Seatbelts prevent passengers from getting lost in the vehicle.
• Seatbelts protect occupants from the effects of inertia during sudden stops or collisions.
