A push or pull on an object is a _____.
What is force
100
______ is a property of a moving object that causes it to continue moving.
What is momentum
100
Movement that includes both speed and direction is_____.
What is velocity
100
_______ resists the motion of two surfaces in contact.
What is friction
100
Objects resists a change in motion. This property is called_____.
What is inertia
200
_______ occurs when an object's speed changes from one rate to another over a certain period of time.
What is acceleration
200

Two billiard balls collide and move in opposite directions. What law of motion is this?

What is Newton's 3rd Law of Motion

200

A car continues moving until the driver brakes suddenly. What law of motion is this?

What is Newton's 1st Law of Motion

200

A student uses force to throw a basketball across the basketball court. This change in motion is related to the mass of the ball and the force used to move it. What law of motion is this?

What is Newton's 2nd Law of Motion

200
Acceleration is directly related to ______ and ______.
What is force and mass
300
The area of science that studies how energy is transferred from place to place and into different forms is _______.
What is thermodynamics
300
The speed of a bicycle traveling north 48 miles in 4 hours is:
What is 12 mph
300
The speed of a bicycle traveling north 48 miles in 4 hours is 12 mph. The velocity of the same bicycle as it returns home at the same speed would be:
What is 12 mph south
300
Two billiard balls collided. One was stationary. The other was moving at a velocity of 5 m/s. The mass of the billiard ball is .15 kg. The momentum that was transferred to the second ball was:
What is .75 kg x m/s
300
What is kinetic friction?
The force that resists the motion of a moving object.
400
What causes friction?
The rough surfaces on objects or the electrical attractions between the atomic particles in the surfaces.
400
What is Newton's First Law of Motion?
If an object were still, it will remain still. If an object is moving, it will continue to move.
400
What is Newton's Second Law of Motion?
Any change in an object's motion depends directly on the applied force and indirectly on the mass of the object.
400
What is Newton's Third Law of Motion?
For every action there is an equal and opposite reaction.
400
Describe the Law of Conservation of Momentum?
Momentum is not created or destroyed. Without outside forces, when two objects collide, the total momentum is the same before and after the collision.
500
What is the formula for speed?
What is speed= distance/time
500
What is the formula for acceleration?
What is acceleration= (ending speed-beginning speed)/time
500

What is the speed of a bicycle traveling north 56 miles in 8 hours?

What is 7 mph

500
If a person walks 2 miles in 30 minutes in a northerly direction, and then heads straight back at the same speed, what is his or her speed?
What is 4mph
500
What is the formula for momentum?
What is momentum= mass x velocity
