• Speed
• Average Speed
• Velocity
• Acceleration
• Net Force

SPEED

• Speed is how far an object can go in a certain amount of time
• Speed=Distance divided by time.
• 0.4 Miles in 8 Minutes = 0.05Mpm
• Did you know sound can travel 5 times faster in water?

AVERAGE SPEED

• Average speed is the average rate at which an object is going
• Average Speed=Total Distance Divided by Total Time
• 10 Miles in 45 minutes=22 miles an hour
• Did you know the average speed of a skydiver is 124mph?

VELOCITY

• Velocity is the speed at which an object is falling in a certain direction
• Velocity=Distance Divided By Time
• A bus driving 15m/s south
• Did you know that the velocity on Earth is 25,000 miles per hour?

ACCELERATION

• Acceleration is rate at which the velocity changes over time
• Acceleration=Velocity Divided by Time
• 6.7 m/s in 12 seconds=O.56m/s
• Did you know that the Acceleration of free fall on the moon is 1.6 m/s

NET FORCE

• Net force is the combination of all forces acting on an object
• Net Force= Fnet + F1 + F2 + F3...
• 25 N + 20 N = 45 N
• Did you know that when in object is in rest it stays at rest till -
• An unbalanced force hits it?
