Force
Which has more friction, rubber, ice, or plexiglass?
rubber
Which vehicle will take more force to stop, a semi truck or a smart car?
A semi truck!
The amount of matter in an object is called its...
mass
If a car is traveling 5 m/s carrying 50 kg, how much force or newtons is it displaying?
F=ma so the force is 250 N
Mr Raigoza comes in at 100 kg and 300 N? What is Mr. Raigoza's acceleration?
Mr. Raigoza's acceleration is 3 m/s
What is required to change the velocity of an object?
force
What are the 5 ways an object can move?
Start, Stop, Speed Up, Slow Down, or Change Direction
To apply a force
Exert
You are playing pool. You hit the white ball and it hits a solid blue ball that is still. What strength and direction of force is exerted on both objects?
Equal but opposite forces.
An empty shopping cart and a full shopping cart both increase speed by 2m/s. Which one experienced the greater force.
The full cart because it has more mass.
To stop an object, what direction and strength of force is needed?
Same strength force in the opposite direction.
Which chair experienced the strongest force? (All had same change in velocity, Mass Blue=12, Mass Red=12, Mass Yellow=10
Blue and Red Chairs
The force that slows down motion between touching objects.
friction
A pod hits a space station. The space station is much more massive than the pod. The pod experiences a much stronger force than the station. True/False
False
False, the Great Sir Fig Newton has incredible cookies but he did not work with Galileo.
To speed up an object, the strength and direction of force should be:
in the same direction of the object's motion
Speed with direction
Velocity
when 2 objects hit each other
collision
Two objects who have the same mass experienced an unknown force. Object A speed up by 3 m/s and object B slowed down by 3 m/s. Which object experienced the stronger force?
Messi kicked a soccer ball and it moves at 5 k/m, Mia stop a soccer ball that was moving at 10 k/m. Who exerted more force on soccer ball?
Mia
To start an object moving, the force must come from:
any direction
According to Newton's 3rd Law, Motion can be observed in?
In Pairs or Action and Reaction
The Newton's first law can be called the Law of ?
Inertia
There is a collision between a bug and a car. The bug experiences a greater change in velocity because...
it has a much smaller mass
Daily Double: If car A is 50 kg and is going 5 m/s, what is the Force (Newton of the car? If car B is 10 kg and is going 10 m/s what is the Force (Newton)?
When car A and car B collide what is the net force (Newton)?
The smart car because a lesser mass needs less force to have a greater change in velocity.
Car A: 250 N
Car B: 100 N
Net Force: 150 N
