Distance

• How much ground an object has covered

3
Velocity

• How fast an object is going in a certain
  direction.

4
Acceleration

 

• How quickly an object slows down or speeds up.

5
Force

• A push or pull that causes an object to move,
  stop, or change direction.
• The larger the weight, the larger the
  force.
• The larger the force, the larger the
  acceleration.

• Car passes bike at about 25 seconds B
• Plane needs about 2000 ft to take off
• MOTORCYCLE
• top speed 175 MPH (280 km/hr or 80 m/sec).
• CAR
• top speed 200 MPH (325 km/hr or 90 m/sec).
• JET FIGHTER top
  speed 1,400 MPH (about MACH 2)
• take off speed 200 MPH.

Jet Fighter versus Car versus Motorcycle

• MOTORCYCLE Accelerates fastest off the starting
  line
• (because it is the lightest). But its top speed
  is only about 175 MPH (280 km/hr or 80 m/sec).
• CAR Accelerates second fastest off the starting
  line (because it is the next lightest).
• But top speed is only about 200 MPH (325 km/hr
  or 90 m/sec).
• JET FIGHTER Slowest of the starting line (it is
  by far the heaviest). But is accelerates for the
  longest time - 0.6 g for more than 25 seconds.
• But top speed MACH 2 or 1,400 MPH with a take
  off speed of about 200-250 MPH.
