**Newton’s 1st Law of Motion**

Object in motion stays in motion

2
**Newton’s 1st Law of Motion**

And Objects at rest stay at rest

3
**Newton’s 1st Law of Motion**

Until they are acted upon by unbalanced forces.

4
**Inertia or Newtons 1st Law**

Tendency for an object to stay at rest or moving in a straight line at a constant speed. The mass (m measured in kg) of an object determines its inertia Inertia comes from the Latin word meaning lazy.

5
**Newton’s 2nd Law of Motion**

Force = Mass X Acceleration F=ma Weight (pull of gravity) is a commonly measured force, calculated by F=mg, g is the acceleration due to gravity 9.8 m/s2

6
**Newton’s 2nd Law of Motion**

The greater the mass of an object, the greater the force required to change its motion.

7
**Newton’s 2nd Law of Motion**

The greater the acceleration of an object, the greater the force required to change its motion.

8
**Formula chart says F=ma, m is mass in kg, a is acceleration in m/s2. **

11 The frog leaps from its resting position at the lake’s bank onto a lily pad. If the frog has a mass of 0.5 kg and the acceleration of the leap is 3 m/s2, what is the force the frog exerts on the lake’s bank when leaping? A 0.2 N B 0.8 N C 1.5 N D 6.0 N Formula chart says F=ma, m is mass in kg, a is acceleration in m/s2. So, .5 kg x 3 m/s2= 1.5 N

9
**Newton’s 3rd Law of Motion**

For every action force there is an equal and opposite reaction force.

10
**Newton’s 3rd Law of Motion**

All forces come in action-reaction pairs Ex: feet push backward on floor, the floor pushes forward on feet

11
**27 A ball moving at 30 m/s has a momentum of 15 kg·m/s**

27 A ball moving at 30 m/s has a momentum of 15 kg·m/s. The mass of the ball is — A 45 kg B 15 kg C 2.0 kg D 0.5 kg Formula Page says that Momentum = Mass x Velocity So 15 kg.m/s = M x 30 m/s solving for M it is:
