The Law of Inertia states that an object at rest tends to ​ (a)   and an object in motion tends to ​ (b)   (with the same speed and in the same direction) unless acted upon by an ​ (c)  

• velocity

• tenacious slowing

• stay at rest

• stay in motion

• outside force

How are mass, gravity, and inertia related?

Groups:

(a) More Mass

,

(b) Less Mass

• Less inertia

• Less gravity

• More Inertia

• 
• More Gravity

On Earth: due to (a)   , we must continue applying force otherwise an object will eventually stop moving.

• energy

• efficiency

• friction

• mass

While you’re ice-skating with your friends, you push off from one end of the rink and slide forward. Based on Newton’s first law of motion, what is true?

• You will lose your balance and fall over before your reach the middle of the ice rink.

• You will continue to slide across the ice until a force makes you stop or change direction.

• The force of gravity will make you keep your velocity until your friends make you stop.

• The size of your ice skates will determine how quickly or slowly you travel across the ice.
