Christmas Scenario: Imagine Santa's sleigh is flying in a straight line delivering presents. According to Newton's First Law of Motion, what would happen to the sleigh if the reindeers stop exerting force?

• The sleigh would slow down

• The sleigh would speed up

• The sleigh would continue in a straight line at the same speed

• The sleigh would change direction

Newton's First Law of Motion: Give an example of Newton's First Law of Motion in a Christmas scenario.

• A Christmas ornament rolling uphill without any force applied

• A Christmas card sliding across a table without any external force

• A sled coming to a stop on a snowy hill without applying the brakes

• A toy car continuing to move forward after the push is stopped

Santa is trying to deliver presents on Christmas Eve. If Santa's sleigh is considered as 'm' and the acceleration due to his reindeers is 'a', what is the formula to calculate the force 'F' required to move the sleigh according to Newton's Second Law of Motion?

• F = m/a

• F = mv

• F = 1/2ma

• F = ma

Santa's Sleigh Motion: Define each variable in the formula for Santa's Sleigh Motion, which follows Newton's Second Law of Motion.

• F = force of reindeers, t = time taken, v = velocity of the sleigh

• F = frequency of Santa's 'ho ho ho', m = mass of the gifts, a = area of the sleigh

• F = friction of the sleigh on snow, m = momentum of reindeers, a = angle of the sleigh's flight

• F = force of reindeers, m = mass of the sleigh, a = acceleration of the sleigh

Santa is trying to accelerate his sleigh to deliver gifts. If the combined force of his reindeer is 20N and the mass of the sleigh with gifts is 5kg, what would be the acceleration?

• 2 m/s^2

• 8 m/s^2

• 4 m/s^2

• 10 m/s^2

Santa's Sleigh Motion: State Santa's sleigh motion principle, similar to Newton's Third Law of Motion, in your own words.

• For every gift dropped, there is an equal and opposite uplift to the sleigh.

• For every gift dropped, there is a greater uplift to the sleigh.

• For every gift dropped, there is no uplift to the sleigh.

• For every gift dropped, there is a smaller uplift to the sleigh.
