The rate at which an object moves from one place to another (no direction)
(a)
A person is swinging a yoyo around on the International Space Station. What type of force keeps an object moving in a circular path and pulls it towards the center? Note: Spelling counts, use all lowercase letters and it is one word. Use your SSN!
(a)
What best describes what is happening in the motion graph?
The object is not moving- velocity is zero
The object is moving at a constant velocity
The object is slowly stopping.
The object is accelerating
What is happening in the motion graph?
The object is not moving.
The object is slowing down
The object is speeding up.
The object is going at a steady pace.
What best describes what is happening in the motion graph?
The object is not moving- velocity is zero.
There is a constant velocity and the object is moving.
There is constant acceleration and the object is moving.
The object is slowly coming to a stop.
What best explains what is happening in the motion graph?
The object is not moving and velocity is zero.
There is a positive acceleration and the object is slowly increasing speed.
There is zero acceleration because velocity constant.
The object is slowly increasing velocity.
What is happening in the motion graph?
The object is not moving
The object is accelerating.
The object has a constant speed.
The object is slowly coming to a stop
What is happening in the motion graph?
The object is not moving.
The object is slowly increasing speed. (Acceleration)_
The object is decreasing velocity and slowing down. (Negative acceleration)
The object is moving at a constant speed (constant velocity)
