Forces
A force directed towards the center of a circle that keeps an object moving in a circle
What is centripetal force?
What causes your body to want to continue to move in a straight line.
What is Newtons 1st law?
A spinning body will stay spinning, a non-spinning body won't start spinning, unless acted upon by an unbalanced torque.
What is the rotational version of Newton's 1st Law?
This force provides the centripetal force that keeps a satellite in orbit moving in a circle?
What is gravitational force?
What fg means on a diagram.
What is gravity?
A fictional "force" caused by a body's desire to continue in a straight line.
What is Centrifugal force?
When an object spins around an internal axis continuously.
What is rotational motion?
If it wasn't for friction or air resistance, this is what would happen to a spinning top.
What is spinning forever?
T or F: Because energy is always conserved, a smaller object must spin faster to have more energy.
What is false?
What Ff means on a diagram.
What is Friction?
Which of the following is NOT a rotational quantity used in physics?
Force, Angular velocity, Torque, or Moment of Inertia
What is Force?
Motion that involves the sliding of an object in one or more of the three dimensions, X, Y, or Z.
What is translational motion?
Where an object spins around an internal axis in a continuous way.
What is is a correct definition of rotational motion?
Fc = mvˆ2/r
What is the equation for centripetal force?
What Ft means on a diagram.
What is tension?
What keeps a ball on a string in its place over your head when you whirl it.
What is tension?
This is what happens when a spinning ice-skater with arms outstretched brings her arms close to her body.
What is she spins faster?
This is is one way you might increase the stability of an object.
What is lower the center of gravity?
A spinning body will stay spinning, and a non-spinning body won't start spinning unless acted upon by an unbalanced torque.
What is Newton's first law when applied to a spinning object?
What was the original name of HCA?
What is Just Right Academy?
A force that acts off center and causes another object to spin.
What is a torque?
Because your body wants to keep going in a straight line, as explained by Newton's 1st Law.
Why do you feel a centrifugal force if it isn't real?
Right after the center of gravity passes past the base of the object.
How can we tell, using the center of gravity of an object, when the object has reached its tipping point?
When you're whirling a ball on a string, this SPECIFIC force keeps it moving in a circle?
What is tension force?
Writing Fc on a free-body force diagram.
What is a mistake?
