if only gravity is acting on you if you jump out of a plane.
What is free fall?
100
An object remains in motion and a object remains in rest.
Newton's First Law.
100
If you are pushing an empty cart you only have to exert a small force. Bu if the cart is full then it will not accelerate it all the way.
Acceleration Depends On Mass
100
This law states, anytime objects collide, the total amount of momentum stays the same.
the law of conservation of momentum

"A stop-action photo shows a table tennis ball and a golf ball fall at the same rate even though they have different masses"
Figure 1
200
The tendency of an object to resist being moved or any change in motion.
Inertia
200
"The acceleration of an object depends on the mass of the object and the amount of force applied."
Newton's Second Law
200
If you push with all the same force with a full shopping cart and a full shopping cart then the mass will in crease and the acceleration will decrees.
Acceleration Depends On Mass

This figure shows "The parachute increases the air resistance of this skydiver and slows him to safe terminal velocity"
Figure 4
300
The constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity
Terminal velocity
300
When one object exerts a force on another object an equal force comes back.
Newton's Third Law
300
If you give a cart a hard push it will go fast if it is empty, if it is full then it will have less speed.
Acceleration Depends On Force.

F=m*a

This figure shows "Astronauts appear to be weightless while they are floating inside the space shuttle but that are not weightless"
Figure 6

The curved path that an object follows when throw, launched, or otherwise projected near the surface of earth
Projectile Motion
400
An object remains in motion and at a constant speed unless acted by an unbalanced force.
Newton's First Law
400
If you push an empty cart compared to a full cart then you will feel the difference. the speed will last longer but it has less velocity.
Acceleration Depends On Force.

who questioned Aristotle's idea about falling objects?
Galileo Galile

This figure shows "The moon stays in orbit around Earth because Earths gravitational force provides a centripetal force on the moon
Figure 8

A quantity defined as the product of the mass and velocity of an object
Momentum
500
if an object acts on an object then the same amount of force comes back.
Newton's Third Law.
500
If the force applied to the carts is the same, the acceleratio of the emty cart is greater than the acceleration of the loaded cart.

This figure shows "Air resistance usually causes a feather to fall more slowly than an apple falls. But in a vacuum, a feather and an apple fall with the same acceleration because both are in free fall.
