The glue bottle is at rest (Balanced) until the boy picks it up
The boy picks up the object at rest (glue bottle) causing a change in force.
Newtons first law says that an object that is at rest stays at rest and an object in motion stays in motion until an unbalanced force acts upon it
Glue stick and boy
The car is in motion (balanced) until the car crashes into the truck
The car and the semi-truck
Weight and gravity
The truck is in motion untill the car colides with the truck (unbalanced)
The size and mass of the tennis ball is less than the basketball which means that when hit with the same amount of force it will go farther
the acceleration of the object depends on its mass and the amount of force applied to it.
Tennis ball vs Basketball
The basketball has a greater mass than the tennis ball, when hit with the same amount of force it will go less distance because of the mass of the ball
The elephant is 100x the size of the squirel it will go less distance when pushed with the same amount of force
Elephant vs Squirel
When the squirel is pushed with the same amount of force it will go farther becasue it has less mass than the elephant
Newtons thrid law says that for every action there is an equall magnitude and opposite in direction
The action force is that the weight is being dropped.
The reaction force is that gravity pulls the weight down.
