The FOUR Fundamental forces
What is Gravitational, Electromagnetic, Strong Nuclear, Weak Nuclear
State Newton's First Law
What is An object at rest remains at rest and an object in motion maintains its velocity unless it experiences a net force. (Law of Inertia)
State Newton's 2nd Law
What is the unbalanced force acting on an object equals the object’s mass times its acceleration. (F=ma)
The force needed to accelerate a 30 kg snow machine 10 m/s2
What is 300 N
Unit for MASS.
What is kg, g
State Newton's 3rd Law
What is for every action there is an opposite and equal reaction.
This always comes in a pair
What is Force
The tendency for an object to resist motion
What is Inertia
The equation to solve for acceleration
A = F / m
The mass of a hockey player that is accelerating at 9 m/s2 and hits another person with a force of 900 N
What is 100 Kilograms (kg)
Unit for Velocity.
What is m/s
According to Newton's 3rd Law, the two pair of forces that act on an object are called
What is ACTION and REACTION Forces
Apposes all motion
What is Friction
The two factors that effect inertia
What is Mass and Velocity
Explain the graph pertaining to Newton's 2nd Law
What is as mass INCREASES acceleration DECREASES.
What is as mass DECREASES acceleration INCREASES.
The acceleration of a cart that has a mass of 0.5 kg and a force of 5 N
What is 10 m/s2
Unit for Acceleration.
What is m/s2
As a soccer ball is accelerating towards Earth (action Force) what is accelerating towards the ball (Reaction Force)
What is the Earth accelerating towards the ball.
Friction between stationary objects
The net force if you push a cart to the right with 5N of force and a friend pushes the cart to the left with 5N of force
What is 0 N (Balanced Forces)
Which object accelerated the slowest?
What is Object A
The force on a kickball that has a mass of 1 kg to accelerate 20 m/s2
What is 20 N
1 N = 1 _________
What is kgm/s2
This happens when air resistance and weight are equal, the object stops accelerating and reaches its maximum velocity
What is Terminal Velocity
The tool used to calculate Force of Friction in the friction lab
What is a Spring Scale
The type of force that causes motion
What is Unbalanced Force
Which object has less mass?
What is object B
The mass of an object that needs a force of 5,000 N to increase its speed from rest to 100 m/s in 2 seconds?
What is 100 kg
Units for Weight.
What is a Newton
(Thinking of Newton's 3rd Law Lab) This happened when the gold glider hit the stationary red glider
What is the gold glider bounced off the red glider sending the red glider one way and the gold glider back where it came from.
