Summative-Acceleration+Isacc Newton

Question 1

What is the difference between speed, velocity, and acceleration?

Answer 1

Speed is the distance traveled in a certain time. Velocity is the distance traveled in a certain time in a certain direction. Acceleration is the rate at which an objects velocity increases.

Question 2

What do you do to find the final speed if you are given the acceleration.

Answer 2

If you know what the initial speed is, you can plug the equation in and try to guess and check for the missing variable. (final speed)

Question 3

What is Newton’s first law? Provide an example:

Answer 3

An object that isn’t moving will stay still, while a moving object will stay moving unless there’s an unbalanced force. An example is a car that is coming down a hill and hits a stationary car.

Question 4

What is Newton’s second law? Provide an example anf the formula:

Answer 4

The smaller the mass, the greater the acceleration when a force is applied. The greater the force there is on an object, the greater the acceleration. Formula=ma (mass Xacceleration) An example is the wheels on your car creating friction against

Question 5

What is Newton’s third law? Provide an example:

Answer 5

For every action, there is an equal opposite reaction. An example of this is a rocket that takes off. The fuel from the rocket is pushing downward, causing the rocket to go upwards into space.

Question 6

Define Free fall:

Answer 6

When only gravity acts upon an object.

Question 7

Define intertia:

Answer 7

A tendency to do nothing or remain unchanged.

Question 8

Define terminal speed:

Answer 8

When an object free falls at max speed and can’t go any faster.

Question 9

Define air resistance:

Answer 9

The resistance of forces to an object in motion.

Question 10

What are some key words in order to determine Newton’’s 3rd law?

Answer 10

Force, lifting objects
