1. newtons first law of motion is also known as the law of
2. newtons first law says that

a. an object that is not moving, or is at
will stay at
b. an object that is moving will keep moving with constant
which means at the same
and in the same
unless
c. an
force acts on that object.

1. what is inertia?
2. what property of an object determines how much inertia it has?
3. which of the following has more inertia?

a. bowling ball or tennis ball
b. hammer or feather
ii. newtons second law of motion

1. newtons second law of motion is also known as the law of
2. newtons second law says that when an

force is
applied to a
it causes it to
the acceleration. 9.

1. the greater the force that is applied, the

the acceleration. 10. if
the lesser the force that is applied, the
acceleration.
the same force is applied to an object with a large mass, it will have a
acceleration.

1. if the same force is applied to an object with a small mass, it will have a

acceleration.

Explanation:

1. Newton's first law is the law of inertia. An object at rest stays at rest and an object in motion stays in motion with constant velocity (same speed and direction) unless an un - balanced force acts on it. Inertia is the tendency of an object to resist changes in its state of motion, and mass determines the amount of inertia. Heavier objects have more inertia.
2. Newton's second law is the law of acceleration. It states that when an un - balanced force is applied to a mass, it causes it to accelerate. The greater the force, the greater the acceleration; the lesser the force, the lesser the acceleration. For the same force, a large - mass object has a small acceleration and a small - mass object has a large acceleration.
