Going in Circles
This word means "center seeking"
What is centripetal?
6.67 X 10-11 N m2/kg2
What is the Universal Gravitation Constant (G)?
Catching a ball and a good football tackle are examples of this type of collision.
What is inelastic?
This is defined as the change in momentum of an object.
What is impulse?
This is the formula used to calculate the centripetal acceleration of an object moving in a circle.
What is v2/r? (What is tangential velocity squared divided by the radius?)
This happens to the gravitational force when the mass of one object doubles and the other mass remains the same.
What is doubles?
Bumper cars crashing and a ball hitting a bat are examples of this type of collision.
What is elastic?
This is the impulse of a 0.5kg ball that is kicked from rest to a speed of 20 m/s.
What is 10 Ns?
Every object on a rigid rotating body has the same amount of this velocity.
What is rotational velocity?
This happens to the gravitational force when the distance between two objects doubles and the masses remain the same.
What is one-fourth (1/4)?
This states that the total momentum before a collision equals the total momentum after the collision.
What is the law of conservation of momentum?
This is the relationship between force and time of impact.
What is inverse?
Two people are standing on a playground merry-go-round that is rotating, one on the outside and one towards the middle. This one has the greatest tangential velocity.
What is the outside person?
This happens to the gravitational force when the mass of both objects double and the distance between them doubles.
What is no change?
If mass is added to a moving object while the momentum stays constant, this happens to the velocity.
What is decreases?
An airbag in your car reduces the force on your body by doing this.
What is increasing the time of impact?
Centripetal acceleration and centripetal force are always pointed in this direction on an object that is rotating.
What is toward the center of the circle?
This happens to the gravitational force when the mass of both objects double and the distance between them is halved?
What is 16 times the force?
This is the relationship between mass and velocity when determining momentum.
What is inverse?
This is the time required for a can crusher to exert a 60 N force on a can resulting in an impulse of 15 N s.
What is 0.25 s?
