This Law of Motion states that the acceleration of an object is in the same direction as the net force on the objects.
What is Newton's 2nd Law?
100
This frictional force opposes the motion of two surfaces sliding past one another.
What is sliding friction?
100
We are effected by the gravity by the supermassive black hole at the center of our galaxy. This is why we don’t feel it strongly.
What is the distance between us and the black hole?
100
Acceleration toward the center of a curved or circular path is known as this.
What is centripetal acceleration?
100
The law of Physics that states that the momentum of an object does not change unless it’s mass, velocity, or both change is known as this.
What is the Law of Conservation of Momentum?
200
This is the mathematical expression of Newton’s 2nd Law.
What is F=ma?
200
A friction-like force that opposes the motion of objects moving through the air is known as this.
What is air resistance?
200
The gravitational force exerted on an object is known as this.
What is weight?
200
The net force exerted towards the center of a curved path is known as this.
What is centripetal force?
200
Two objects are of the same mass, shape, and height from the ground. One object is dropped and the other is launched horizontally away. These object will strike the ground relative to each other.
What is the same time?
300
The force that opposes the sliding motion of two surfaces that are touching each other.
What is friction?
300
The amount of air resistance an object experiences is dependent on these 3 factors.
What are size, shape and speed of the object?
300
The mass of an object on the moon is this compared to its mass on the Earth.
What is the same?
300
The law of Physics that states when an object exerts a force on a second object, the second objects exerts a force on the first object that is equal in strength but opposite in direction is known as this.
What is Newton’s 3rd Law of Motion?
300
An object collides with second more massive object at rest. The second object will move away from the first object with a velocity that is this compared to the velocity of the first object.
What is a smaller velocity?
400
This is an explanation for the source of friction between two surfaces.
What is the physical interaction between the microwelds on each surface?
400
This situation occurs on a falling object when the force of air resistance equals its downward force due to gravity.
What is terminal velocity?
400
The weight of an object on the moon is this compared to its weight on the Earth.
What is less?
400
The product of an objects mass and its velocity is known as this.
What is momentum?
400
Increasing the downward force on one object that is resting on a surface on another surface will increase this when the one object moves on top of the other.
What is friction?
500
This frictional force prevents two surfaces from sliding past each other.
What is static friction?
500
The attractive force between any two objects that depends on the masses of the object and the distance between them.
What is gravity?
500
These are the two components of projectile motion.
What are vertical and horizontal components?
500
The total momentum before and after a collision is this.
What is equal?
500
A feather and an apple fall from the same height, in a vacuum. The feather hits the ground at this time relative to that of the apple.
