Forces and Projectile motion
Newton's Laws
Speed and Velocity
Acceleration and Momentum
100
A force of attraction, all matter experiences this
What is gravity
100
All objects fall at a speed of 9.8m/s^2
What is free fall acceleration
100
An object in motion will stay in motion unless acted upon by an unbalanced force, and an object in rest will remain at a rest unless acted upon by an unbalanced force
What is the law of inertia
100
how fast an object is moving
What is speed
100
The rate of change in velocity
What is acceleration
200
The amount of matter in an object
What is mass
200
If two equal forces are applied to opposite sides of an object what is this called
The forces are balanced
200
For every action there is an equal and opposite reaction
What is newton's third law
200
how fast an object is going and the direstion its traveling in
What is velocity
200
What two factors affect acceleration
What are change in velocity and time
300
the amount of gravitational force on an object
What is weight
300
If two forces are applied on opposite sides but one force is greater what is this called
the forces are unbalanced
300
acceleration is determined by...
The amount of force applied and the mass
300
The two factors that determine velocity
What are time and distance
300
What two things determine momentum
What is mass and velocity
400
What two variables affect gravity
What is mass and distance
400
If a car and a rock were dropped out of a plane which object would hit the ground first?
Neither they would hit the ground at the same time
400
If you roll a ball across the ground it will always eventually stop, what causes this?
What is friction
400
How far an object has moved from the starting point, does not equal total distance
What is displacement
400
when an object is slowing down, the direction of the acceleration is in the opposite direction of the objects motion
What is the rule of the thumb
500
What would happen to the force of gravity between two objects if the distance was doubled in length
The force between the objects would decrease by one half
500
According to the third law every action and reaction are equal so that means if they act together they would balance each other out, so how could the forces be unbalanced?
The forces do not always act on the same objects, this is how objects move.
500
If a car travels 270 m in 45 seconds what is the velocity of the car
What is 6 meters per second
500
In a race a car starts out going 40 miles per hour and finishes going 120 miles per hour in 60 seconds, what is the acceleration?
What is 1.33 meters per second^2
