200
Net Force
What is is the overall force acting on an object?

Non-contact Force
What is a force applied to an object by another body that is not in direct contact with it?
200
In which situation are the forces acting on the object balanced? A. A car turns a corner at a constant speed. B. A minivan slows as it approaches a stoplight. C. A hot-air balloon rises at a constant speed. D. A skateboarder picks up speed as she skates down a hill.
What is C. A hot-air balloon rises at a constant speed?

In outer space, a small ball of rock and ice travels for thousands of years. Its motion does not change in any way during that time. As it approaches the solar system, however, it comes under the influence of the Sun's gravity and its motion begins to change. Which principle does this demonstrate? a. Every action has an equal and opposite reaction. b. An object in motion moves in a straight line at a constant speed until acted on by a net force. c. Matter may change form but not be created or destroyed. d. In nature, favorable traits tend to aid in survival and reproduction.
What is b. An object in motion moves in a straight line at a constant speed until acted on by a net force. ?

Force
What is strength or energy as an attribute of physical action or movement?
300
Newton (n)
What is the SI unit of force?
300
Normal Force
What is the force exerted by an object to balance an outside force acting on it?
300
The net force acting on an object is 0 N. Which of the following best describes the motion of the following object? A. The object is not moving. B. The object is moving at a straight line at a constant speed. C. The object is slowing down. D. The object's motion is not changing.
What is D. The object's motion is not changing. ?

***REFER TO PAGE 118 NUMBER 8*** Tamara rode her bike to her friend's house. The distance-time graph shown above (pg 118) represents Tamara's trip. Describe Tamara's speed and the net force acting on her bicycle between 15 min and 20 min. Include the proper units.
What is Tamara's speed is constant (ON) at 3 k/m ?
400
Friction
What is the resistance that one surface or object encounters when moving over another?
400
Newtons first law of motion
What is every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
400
Equilibrium
What is a state in which opposing forces or influences are balanced?
400
Sean pushes a parked car with a force of 80 newtons (N). The car does not move. Which of the following best describes the force that the car exerts on Sean? A. the same amount of force as Sean exerts B. less force than Sean exerts C. no force D. more force than Sean exerts
What is A. the same amount of force as Sean exerts?
400
Gabe kicked a soccer ball across a field. The ball rolled for a while but eventually stopped. If Newton's first law is true, it seems that the ball Gabe kicked should continue rolling forever. Why does the ball stop?
What is The soccer ball that Gabe kicked stops because friction causes it to slow down. Friction is an unbalanced force?
500
Gravity
What is the force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account?
500
Newtons second law of motion
What is he acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object?
500
Give an example for each of Newtons laws.
What is Law 1.) When a car is going and suddenly stops, the passengers will move forward. Law 2.) When you throw two weights of different masses at the same speed the lighter one moves faster. Law 3.) When a person slams the wall with their fist. The force applied by the person through their fist on the wall is equal to the force applied by the wall on the fist. **Anything along the line of these count**

500
If you hit a home run in space, what would happen?
What is Friction and gravity stay in motion. If the ball is hit into outer space, it would move in a straight line at a constant speed until it came under the influence of gravity from another body such as a star or planet?
