Andrew plays trumpet in the concert band. He holds the trumpet still at his side until it is time for him to play. When it is time, he brings the trumpet up to his mouth and starts to play. According to Newton’s first law of motion, the trumpet starts moving because a net force overcomes the trumpets ________.



The trumpet starts moving because a net force overcomes the trumpet's inertia.

Speed equals distance divided by __________ .



Time

Josh is a basketball player for his high school team. During practice the team works on passing as fast as they can. If Josh throws a 20oz basketball with the force of 60N. How fast did the ball accelerate?            (F = M x A)

3 m/s^2

What type of friction happens when an object passes through something such as air or liquid?

Fluid Friction

500

________ is the formula for finding Acceleration (using speed).

Final speed - initial speed / time

What is one way that Newton's 3 Laws applies to a person hitting a croquet ball with a mallet?

I. The ball will remain at rest until the unbalanced force of the mallet acts upon it

II. The mallet will cause a force upon the ball which will accelerate it. The acceleration is determined by the force and the mass of the ball

III. The action is hitting the ball and the reaction is the ball back on the mallet

At 2s a ball is at 16km. Once the ball reaches 4s it is at 48km. What is the speed of the ball at 2s and at 4s?

What is the acceleration from 2s-4s?

2s: 8km/s

4s: 12km/s

Acc: 2 km/s^2
