Science Module 2 Test Reveiw

Question or Hint Answer or Word

If you try to slide two objects past each other, a small amount of force will result in no motion. The force of friction is greater than the applied force. Static Friction (wrong answers: Kinetic Friction, Friction, Pendulum)
You do not need to apply quite as much force to keep the object sliding as you needed to break free of static friction originally. Kinetic Fiction (wrong answers: Static Friction, Friction, Centripetal Force)
When we walk, we push back against the ground allowing us to move forward. Without friction, our feet would slip, and walking would be impossible. Helpful Friction
We need friction between car tires and the road for the car to travel the road safely, but prolonged friction results in worn-out tires. Harmful Friction
A center-directed force that continuously changes the direction of an object to make it move in a circle. Centripetal Force
the force perpendicular to the velocity of an object moving along a curved path. Centripetal Force
Galileo became intrigued with the pendulum by watching the movement of a swinging chandelier in a Pisa cathedral. Pendeuum
