1 Newtons Laws Online Activity Debrief Tahoma Jr. High 8 th Grade Science Maple Valley, WA

2 1. Friction occurs with the movement of two objects in _____________ with each other. 2. Friction is a force that is in the ______________ direction of travel. 3. Static friction occurs when two objects are in contact and ___________ moving. 4.Kinetic friction occurs when two objects are in contact and ____________ against each other. contact opposite not moving

3 5. Friction always causes ______________ and ________________ of surfaces. 6. When an object is falling through the air and the drag (resistance) equals the pull of gravity, ____________ ____________ has been reached. heat wearing terminal velocity

4 7. What is Newtons first law? An object at rest or in uniform motion will stay at rest or in uniform motion until a net force is applied. In simple terms: The motion of an object will not change unless a force is applied

6 8. What is meant by a net force? The overall force on an object when all the individual forces acting on an object are added together. If 15 Newtons of force are applied to the right and 20 Newtons of force are applied to the left, the net force will be 5 Newtons to the left 15N 20N net of 5N to the left

7 9. What is meant by a balanced force? When forces in opposite directions are equal 10N (think of a balanced see-saw… which is a bunch of unbalanced forces balancing each other!) R R E E

8 10. The more force you apply to an object, the greater it will _____________________. 11. An unbalanced force will cause _______________, or______________________________. 12.The more an objects mass, the greater the ___________________ will have to be to make it _________________ (speed up). accelerate (speed up) force applied accelerate accelerationdeceleration change in direction (vector)
