Laws of Motion (Newton)

What is Newton's first law of motion?

• two objects interact, they apply forces to each other of equal magnitude and oppotsite direction

• force on an object is equal to its mass times its acceleration

• object will not change motion unless a force acts upon it

• when two objects collide and make a sound creating motion

What is Newton's third law of motion?

• when two objects collide and make a sound creating motion

• when two objects interact, they apply forces to each other of equal magnitude and opposite direction

• force on an object is equal to its mass times its acceleration

• will not change its motion unless a force acts upon it

What is Newton's second law of motion?

• two objects interact, they apply forces to each other of equal manitude and opposite direction

• when two objects collide and make a sound creating motion

• the force on an object is equal to its mass times its acceleration

• an object will not change its motion unless a force acts upon it
