Vocabulary
This terms describes the rate at which an object moves.
The unit that measures speed and velocity.
What is cm/s?
The two requirements to be considered velocity.
What is speed and direction?
The things force can change.
Motion and velocity/speed.
Two objects had the same force exerted on them. They have different masses. This object will move with a higher velocity/speed after the force is exerted.
What is the less massive object?
This term describes speed in a particular direction.
What is velocity?
This is what we add in front of a number with the unit cm/s to identify it as a velocity (direction).
Movement to the right has this in front of it's velocity.
What is a positive sign?
Force is a ____ or ____
What is push or pull?
A black office chair and a yellow office chair were pushed across a floor with the same force. The black office chair moved twice as fast as the yellow after being pushed. Which office chair had more mass?
What is yellow?
This term describes a push or pull that can change the motion of the object.
What is force?
The formula for speed and velocity.
What is speed & velocity = distance / time?
Movement to the left has this sign in front of it's velocity.
What is a negative sign?
The more force you apply, the more ___ as a result.
What is velocity?
Puck A and B were moving at 2 cm/s on a frictionless hockey rink. They were both pushed by a force of the same strength. Puck A's final velocity was 6 cm/s and Puck B's final velocity was 8 cm/s. What caused the difference in velocity?
What is mass?
This term describes a force between an object and the surface it is moving over.
What is friction?
This unit (cm/s), when paired with a positive number would describe what? (be specific!)
What is velocity to the right or up?
If a soccer ball is moving at +30 cm/s and has a force of 10 applied to the right. The new velocity is...
What is +40 cm/s?
Friction is a _____
A dumpster truck and a Bugatti were at the red light on South Capitol St ready to race. The dumpster truck was much more massive than the Bugatti. In order for them to move at the same velocity, what needs to happen?
The dumpster truck needs to have more force applied to it than the Bugatti.
This term is described as "applying a force."
What is exert?
The unit that goes with force. (think carefully!)
There is no unit for force (yet).
A taki is rolling on the floor at +1 cm/s. Someone comes and blows on the taki in the opposite direction with a force of 10. This is the new velocity...
What is -9 cm/s?
If I apply a force +horizontally and +vertically, what is the direction of the object?
What is diagonally up and to the right?
Puck A and B were moving at a velocity of +20 cm/s. Puck B is more massive than Puck A. A force in the opposite direction hit both pucks. Puck A's final velocity was -10 cm/s. Given Puck B's mass, would Puck B's velocity be more negative or less negative than Puck A's?
What is less negative?
