Newtons laws 2 and 3, also opposing forces

Air Resistance

The upward force on an object falling through the air.

Newton's Second Law

Explains the relationship between mass, force, and acceleration

Air Resistance

Why a feather falls slower than brick.

9.8 m/s^2

The acceleration of gravity on earth.

fall at the same rate

In the absence of air, a penny and a feather that are dropped from the same height at the same time will:

F = M x A

What is the equation that explains Newton's Second Law

Centripital Force

When an object moves in a circular path, what accelerates the object toward the center of the circle.


The path of a projectile is always: (what shape)


For any object, the greater the force applied to it the greater its ________ will be.

Mass and Distance

The size of the gravitational force between two objects depends on their:


As you get farther from the Earth your weight will:


When a force is exherted on a box, an equal and opposite force is exherted by the box. These forces are called _________ forces.

greater mass

Why does a real car have more momentum than a toy car moving at the same speed?


What does the P stand for in the following equation? P = M x V

Newton's Third Law

the statement, "to every action there is an equal and opposite reaction" summarizes:

kg/ms (Joule)

The unit for measuring Momentum is a:

The Law of Conservation of Momentum

When two balls collide, the momentum after the collision can be explained by using:

12 m/s^2

The acceleration caused by a 300N force acting on a 25kg object

15 m/s^2

The acceleration caused by a 3,000N force acting on a 200kg object

Free Fall

An object that seems weightless on or near Earth is actually in:

Horizontally (in a straight line)

If gravity did not affect the path of a horizontally thrown ball, the ball would move:


It's what makes mass and weight different.

50 kgm/s (joules)
