What is a scalar measurement
A quantity with magnitude (number) but no direction
If Jaxson is travelling at 20 m/s, how far will he travel in 4.5 seconds?
90 meters
What is newtons first law
Law of inertia, an object in motion tends to stay in motion and an object at rest tends to stay at rest unless acted on by a force.
Give an example of a motion-related technology and its function.

What is a vector measurement
A quantity with both magnitude and Direction
If Daxon takes 300 seconds to travel 15 meters, what is his speed?
0.05 m/s
Newtons second law
F=ma
the acceleration of an object is proportional to its mass and the force acted on it.
What's the difference between distance and displacement?
Distance = total distance travelled
Displacement = change in position from start to end - shortest total distance.

Newtons third law
for every action their is an equal and opposite reaction
What is the difference between mass and weight?
Mass: the amount of matter in an object
Weight: force of gravity on mass, changes dependent on grav

Kinematics is
The study of motion without considering the forces that cause motion (ex. v = d/t)

Distance = 7m
Displacement = 5m NE

Dynamics is
The study of forces and their effect on motion.

What is the difference between acceleration and deceleration?
Acceleration: speeding up, positive value
Deceleration: slowing down, negative value.
