Warm-up 1. If a toy train has a mass of 1.5 kg & accelerates at a rate of 20 m/s2, what is the amount of force acting on it? 2. Make a Venn diagram comparing/contrasting gravity & friction.

Warm-up 1. If a toy train has a mass of 1.5 kg & accelerates at a rate of 20 m/s2, what is the amount of force acting on it? Force = mass x acceleration force = 1.5 kg x 20 m/s2 30 N = 1.5 kg x 20 m/s2

Warm-up 2. Make a Venn diagram comparing/contrasting gravity & friction.

Warm-up Friction Gravity Provides resistance Both 2 objects rub against each other 3 types Fluid Sliding Rolling Both Pulls 2 objects together Weight = force of gravity Speeds up motion Forces Act on 2 objects Have direction Accelerate Slows down motion Acts in a direction opposite to the objects motion

Newton’s 3rd Law of Motion If one object exerts a force on another object, then the 2nd object exerts a force of equal magnitude in the opposite direction.
