Meters
This is a push or a pull
A Force
This equation helps us calculate forces
F=ma
As you increase the mass, but keep the force the same, what happens to the acceleration.
It decreases
Ruby the cat has a mass of 5kg, and accelerates at 15m/s2 to jump up her cat tower. How strong is the force she jumped with?
F=75N
The amount of matter in a space
Mass
The F stands for this concept
Force
As you increase the Force but keep the mass the same, what happens to the acceleration?
It increases
Mrs. Krebs kicks a kickball, with a mass of 0.54kg, at an acceleration of 222.22m/s2. How much force did she kick the ball with?
120N of force (119.9N)
This is a measurement of the amount of force. Named after a famous physicist.
Newtons, N
How fast something increases (or decreases!) speed
Acceleration
Mass
What happens to the force needed to move on object when the mass increases?
The force needed also increases!
Mason passes the basketball (0.54kg) with a force of 100N. What acceleration does the basketball experience?
185 m/s2
A measurement of speed increasing.
m/s2. Meters per second squared
Speed, but with a direction!
Velocity
a stands for this concept.
Why did the small marble move faster when hit by the large marble, than the large marble did when hit by the small marble?
The small marble was hit with a larger force from the large marble.
A soccer ball is kicked with a force of 300N and has a mass of 0.40kg. How much acceleration did it experience?
750 m/s2
This is a measurement of velocity, how fast something moves.
m/s, Meters per second
Inertia
This equation allows us to calculate acceleration
a=F/m
Compare the amount of force needed to move a washing machine (70kg) and a fridge (135kg).
You need more force to move the fridge.
A full rollercoaster of Storm Chaser at Kentucky Kingdom has a mass of about 500kg, and experiences a max force of 18500 N. How much acceleration is the train experiencing?
37m/s2
