1) Motion is an object's change in position relative to a reference point. An object is in motion when the distance from the reference point changes. If the distance increases you are moving away from the reference point. If the distance decreases you are moving toward the reference point.

2) A frame of reference is a system of objects that are not moving with respect to one another. A reference point is the same thing as a frame of reference. Your motion depends on which frame of reference is used.

3) The speed of an object is the ratio of the distance an object moves to the amount of time the object moves. There are two different types of speed, average and instantaneous. Average speed is computed for the entire duration of the trip while instantaneous speed is measured at a particular instant. The SI unit of speed is meters per second (m/s) and the equation is distance/time (d/t).

4) Velocity is the speed and direction in which an object is moving. Velocity is a vector quantity. Also a change in velocity can result in a change in speed, direction, or both. The difference between speed and velocity is that velocity includes direction.

5) Acceleration is the rate at which velocity changes. Acceleration is also a vector like velocity. You can accelerate in three different ways change in direction, speed, or both. Deceleration is when an object slows down.

6) Acceleration is measured by calculating the change in velocity from the initial velocity to the final velocity and dividing it by the total time.

7) Speed, velocity, and acceleration are related by the fact that they all need time in order to be calculated. Also they all measure the motion of an object and they especially measure the speed of an object. Another thing is that you can't have velocity or acceleration without speed.

8) A positive slope, negative slope, and flat line mean something different on a speed graph than on an acceleration graph because on a speed graph you are measuring distance and time and on an acceleration graph you are measuring speed and time. When it is a positive slope the distance is increasing on the speed graph as speed increases on the acceleration graph. When it's a negative slope they are decreasing. When it's a flat line on a speed graph that means the distance isn't changing and there is no motion, while on an acceleration graph the speed would be constant which means the speed isn't going faster but it is staying the same.

9) The unit for speed is meters per second (m/s). The unit for velocity is meters per second plus direction. Lastly, the unit for acceleration is meters per second squared (m/s/s).

10) The definition of a force in physical science is a push or pull that acts on an object. A force can cause a resting object to move, or can accelerate a moving object by changing its speed or direction.
