Answer 1 – 10 • What is speed? Question 1 - 20 • An object is dropped from rest and falls downward for 5 seconds. What is its average speed? Answer 1 – 20 • What is 10 m/s? Question 1 - 30 • Acceleration of an object must be caused by a force that is this. Answer 1 – 30 • What is not zero? Question 1 - 40 • 2 km equals this many centimeters. Answer 1 – 40 • What are 200,000? Question 1 - 50 • A unit of acceleration. Answer 1 – 50 • What are m/sec2? (any speed/time) Question 2 - 10 • The term used to describe an object speeding up. Answer 2 – 10 • What is acceleration? Question 2 - 20 • The term that refers to an object slowing down. Answer 2 – 20 • What is deceleration? Question 2 - 30 • This may occur when an object is accelerated. Answer 2 – 30 • What is a change in speed, a change in direction or both? Question 2 - 40 • Newton’s first law is also known as this. Answer 2 – 40 • What is the Law of Inertia? Question 2 - 50 • Newton’s Second Law Formula Answer 2 – 50 • What is F=ma Question 3 - 10 • Two horizontal forces are applied to a box, 5 N to the right and 12 N to the left. This is the motion of the box. Answer 3 – 10 • What is 7N to the left. Question 3 - 20 • This is the acceleration due to gravity, numerically. Answer 3 – 20 • What is 9.8 m/s2? Question 3 - 30 • When an object is accelerating due to the force of gravity with no other forces acting on it. Answer 3 – 30 • What is free fall? Question 3 - 40 • The inertial of an object is related to this. Answer 3 – 40 • What is mass? Question 3 - 50 • Gwen rides her bicycle 2.4 km up a steep hill in 8 minutes. This is her speed in km/min. Answer 3 – 50 • What is 0.3 km/min? Question 4 - 10 • If you know the distance traveled and the amount of time it took, you can calculate speed using this equation. Answer 4 – 10 • What is distance divided by time? Question 4 - 20 This is how many centimeters tall a person who is 1.65 meters is. Answer 4 – 20 • What is 165 cm? Question 4 - 30 • The newton is defined as this. Answer 4 – 30 • What is the force that can give a 1 kg mass an acceleration of 1 m/s2? Question 4 - 40 • The amount of change in the speed of an object divided by the amount of time it took to change the speed. Answer 4 – 40 • What is acceleration? Question 4 - 50 • When you throw a ball up in the air, the point where it stops and changes its direction to fall back down, this is zero. Answer 4 – 50 • What is velocity/speed? Question 5 - 10 • This is the formula to calculate free fall distance. Answer 5 – 10 • What is d=1/2gt2 or d=vavgt ? Question 5 - 20 • An apple falls from the top branch of a tree and lands 1 second later. This is the height of the branch. Answer 5 – 20 • What is 4.9 m? Question 5 - 30 • Your science teacher drops a tennis ball out the window and it hits the ground 3 seconds later. This is the height of the window. Answer 5 – 30 • What is 44.1 meters? Question 5 - 40 • You drop a ball from the edge of a cliff. It lands 4 seconds later. This is the balls average speed for the entire fall. Answer 5 – 40 • What is 19.6 m/s? Question 5 - 50 • You drop a ball from the edge of a cliff. It lands 4 seconds later. This is the distance the ball falls. Answer 5 – 50 • What is 78.4 meters?
