What to things must you specify when describing the velocity of an object?
The speed and the direction.
How two things do you need to know to describe the velocity of an object?
Velocity includes speed and direction.
What are the 3 things that can change velocity?
There is basically only ONE thing that can make a velocity change, and that is a force acting on an object.
What two things velocity tell us about an object's motion?
speed and direction.
Why do you need to calculate velocity instead of speed?
Speed and Velocity are two different things . Velocity- "the rate at which an object changes its position." Speed- "How fast an object is moving". To calculate speed and velocity, you first need to calculate distance and time. Velocity is considered to be a more logical term

What two things do the kinetic energy of an object depend on?
KE = mv2 The mass and the squared velocity of the object.

An object that is moving at constant velocity and continues at that velocity unless a net force acts on it illustrates?
That things tend to stay in motion.
What are the things that affect the motion of an object?
Velocity, mass, forces, acceleration, slope, etc.
What to Things do you need to know to describe the velocity of an object?
velocity is what is known as a vector quantity. What this means is it needs both a DIRECTION and a MAGNITUDE for the velocity to be fully described. that's what you need.
How do scientists weigh things in space?
They measure the velocity of the object after applying a accurately measured force.
What is the inertia of motion?
Inertia of motion is the resistance mass has to motion. It also is the resistance in change in momentum. Momentum includes two things: velocity and direction. When an object changes its velocity, the momentum of the object resists the change. Also, when an object does change its velocity, its momentum is directly changed. In general, the inertia of motion is matter's unwillingness to change velocity or momentum.
