An object in motion will stay in motion unless it is acted on by an unbalanced force
What does Newton’s first law state?
100
What is momentum?Momentum is a quantity defined as the product of the mass and velocity of an object.
Momentum is a quantity defined as the product of the mass and velocity of an object.
100
true
True or false? In some collisions, the objects bounce off of each other.
100
Force and mass
Acceleration depends on what two things
100
a= f/m
What is the equation for acceleration?
200
A. why objects fall to earth with the same acceleration
What does Newton’s second law explain? A. Why objects fall to earth with the same acceleration B. Why inertia makes it harder to accelerate a car than a bike C. how forces act in pairs
200
Air resistance
______________ is the force that opposes the motion of objects through the air.
200
Kilograms multiplied by meters per second: kg*m/s
What are the units for momentum?
200
Vertical motion
What type of motion occurs when the ball starts to accelerate downwards?
200
Because they have less mass
Why do new cars pollute the air more than older cars? A. They have more mass B. They have less mass C. They have more velocity
300
C. Friction
Because of A. Air resistance, B. Gravity, or C. Friction, Newton’s First Law is often difficult.
300
If gravity is pulling it down and no other forces are acting on it
an object is in free fall only if what occurs?
300
True
True or false? The total momentum of all the objects in the collision will remain the same before and after the collision
300
Terminal Velocity
____________ is the constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity.
300
B, it has more mass
Why is a heavy object harder to accelerate?.... A.) It has more density…. B.) It has more mass….C.) It has more volume….D.) It has more weight
400
Newton’s Third Law
Newton’s Third Law Which Law states that whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first?
400
The unbalanced force that causes objects to move in a circular path
What is centripetal force?
400
More, harder
The _________ momentum an object has, the ___________ it is to stop the object or change its direction.
400
Stops accelerating
Once air resistance is equal to the downward force of gravity or 0N the object_______________
400
How can conservation of momentum be explained by Newton’s third law of motion? One object acts as an action force and the other object acts as a reaction force. These forces are equal and opposite, and momentum is neither gained nor lost
How can conservation of momentum be explained by Newton’s third law of motion?.
500
false
True or False: The less mass the more inertia
500
A. Weight
What is a measure of gravitational force?....A.) weight….B.) mass….C.) density….D.) volume
500
P = m*v : m= mass of the object in kilograms and v= the object’s velocity in meters per second
What is the equation for momentum?
500
Masses the objects and the distance between them
The size of force depends on the ________ of objects and the _________ between them
500
Gravity
What pulls everything on Earth downwards?
