Newton's Laws Of Motion

Alice Kicks a soccer ball with a 0.5 N of force what force does the bar exert on Alice's foot as she kicks it?

0.5 N

What force would be required to accelerate a 1,100 kg car to 0.5 m/s2 ?

550 N

Application of Newton's second law

The equation for acceleration is :: a= f/m acceleration equals force divided by mass

Inertia

The natural tendency of objects to resist change in motion

Newton's second law

The total net force is equal to mass x acceleration F= ma

Newton's Third Law

For every action, there is an equal and opposite reaction

If Siobhan hits a .25 kg volleyball with .5 N of force, what is the acceleration of the ball?

2 m/s2

Newton's First Law of Motion// Law of Inertia?

An object at rest stays at rest, and an object in motion stays in motion UNLESS acted on by an unbalanced force

Newton's First Law Of Motion states that an object at rest stays at rest, and an object in motion stays in motion unless acted on by an unbalanced force. Which statements describe Newton's first law? Check all that apply.

An overall net force must be applied to an object before it can move. Newton's first law of motion is also known as the law of inertia. Newton's first law applies to an object whether it is moving or not.

Vocabulary

inertia:: property of matter that resists changes in motion Newton's second law:: statement that force is equal to mass times acceleration mass:: measure of the amount of substance in a sample Force:: push or pull Newton's First Law:: objects motion being constant unless acted on by an unbalanced force
