B What is an objects weight proportional to? I How do unbalanced forces cause objects to accelerate? (2Ways) What type of force must What type of friction do you have to overcome to start an object in motion? What is the upward force on a object falling through the air? What force causes objects to slow down? What is a force that opposes motion? What is centripetal force? What does Newton’s second law allow scientists to calculate? Identify Newton’s law that describes a girl pushes a sled and the sled accelerates. Identify Newton’s law for swinging a ball on a string around your head. N G O Complete this phrase For every action there is Explain how to calculate net force. What action is required for a force to be considered a contact force? Whenever an object exerts a force on another object, the second object exerts a force of the same magnitude. What direction does the force go? Which law states the relationship among force, mass, and acceleration? What is the formula for Newton’s second law? What are forces that are equal in size but opposite in direction? What would happen to the ball if gravity did NOT affect the path of a horizontally thrown ball? Why do astronauts in space weigh less than they do on Earth? Identify Newton’s law that describes a balloon flies off when the opening is released. What is the unit for force? When is something a contact sport? Identify Newton’s law that describes gravity causes a ball to fall How are mass and weight related? Identify the law that that describes a book sitting on the table. Answer Sheet B I N What is an objects weight proportional to? MASS What type of force must What type of friction do you have to overcome to start an object in motion? STATIC FRICTION Complete this phrase For every action there is AN EQUAL BUT OPPOSITE REACTION How do unbalanced forces cause objects to accelerate? (2Ways) CHANGE IN DIRECTION OR SPEED What is the upward force on an object falling through the air? AIR RESISTANCE What force causes objects to slow down? FRICTION What is a force that opposes motion? FRICTION What is centripetal force? TRAVELS IN A CIRCLE LIKE AN ORBIT What does Newton’s second law allow scientists to calculate? FORCE, MASS, ACCELLERATION Identify Newton’s law for swinging a ball on a string around your head. NEWTON’S SECOND LAW Identify Newton’s law that describes a girl pushes a sled and the sled accelerates. NEWTON’S SECOND LAW Whenever an object exerts a force on another object, the second object exerts a force of the same magnitude. What direction does the force go? OPPOSITE Which law states the relationship among force, mass, and acceleration? NEWTON’S SECOND LAW When is something a contact sport? WHEN THERE IS A COLLISION/TOUCH Identify Newton’s law that describes gravity causes a ball to fall. NEWTON’S FIRST LAW G O Explain how to calculate net force. IF THE FORCE APPLIED IS GOING THE SAME DIRECTION YOU ADD IT. IF THE FORCES ARE OPPOSING YOU SUBTRACT THEM. What is the formula for Newton’s second law? F=MA What action is required for a force to be considered a contact force? TOUCH What would happen to the ball if gravity did NOT affect the path of a horizontally thrown ball? GO HORIZONTALLY Why do astronauts in space weigh less than they do on Earth? FURTHER FROM THE GRAVITIONAL PULL Identify Newton’s law that describes a balloon flies off when the opening is released. NEWTON’S THIRD LAW What is the unit for force? NEWTON What are forces that are equal in size but opposite in direction? BALANCED How are mass and weight related? PROPORTIONAL Identify the law that that describes a book sitting on the table. NEWTON’S FIRST LAW
