Football - Newton's First Law of Motion

Newtons First Law States:

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an ___________________..

• unbalanced force

• equal and opposite force

• force

• balanced force

The natural resistance of an object to change it's motion is called what?

• velocity

• inertia

• force

• acceleration

What gives an object more inertia?

• more velocity

• less velocity

• more mass

• less mass

Why is mass different from weight?

• Weight is only due to how much matter you are made of and is always the same.

• Mass never changes but weight changes when gravity the attraction of gravity is different.

• Mass is acceleration.

• Weight never changes but mass changes when gravity the attraction of gravity is different.

How can NFL sports officials predict which defensive line will win when two teams line up before a play.

• By measuring the acceleration only of the defensive line.

• By look at which team has less courage.

• By determining who is the most aggressive.

• By measuring the combined mass of the defensive line.
