Why we must wear our seat belts in a moving vehicle.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

When air is released from a balloon, the balloon moves in one direction and the air moves in another direction.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

An empty chair is pushed down a hall. The chair is then pushed down the hall with someone in it but requires more force to maintain the acceleration

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

For every action there is an equal and opposite reaction.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

An object at rest tends to stay at rest and an object in motion tends to stay in motion at a constant velocity unless acted on by an unbalance force.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

If you have a book sliding on a table it will eventually come to a stop.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

The relationship between an object’s mass (m), an oject’s acceleration (a), and the applied force (F) is F=ma. Acceleration and force are vectors. This law requires that the direction of the acceleration vector is in the same directions the force vector.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

Also know as the law of inertia.

• Newton's 1st Law

• Newton's 2nd Law

• Newton's 3rd Law

Objects tend to resist changes in motion. This property is called:

• weight.

• momentum. .

• potential energy.

• inertia

Compared to your weight and mass on Earth, if you were on the moon:

• your weight and mass would be less.

• your weight would be less but your mass would remain the same.

• your weight would remain the same, but your mass would be less.

• your weight would increase, but your mass would remain the same.
