# Motion Review

Interrogative QuerySufficient Response
What is velocity? Speed and Direction
What is speed? Distance and time
Explain displacement. How far something is from its original location
What is distance? The space between two points, or locations
Explain acceleration. Tell three ways an object can accelerate. Acceleration is changing in speed. Gaining speed, losing speed, or changing direction
Explain why deceleration is also acceleration. Deceleration is acceleration because acceleration is any change in speed
What does a flat line on a distance/time graph represent? Time passing but, distance is not changing
Greater slope up means ____________ on a distance/time graph. Greater Distance from original location
Greater slope down means ____________ on a distance/time graph. Lesser Distance from original location
What does a flat line on a velocity/time graph represent? Velocity is constant while time is passing
What does an upward slope on a velocity/time graph represent? Acceleration
What does a downward slope on a velocity/time graph represent? Deceleration or Acceleration
What does constant velocity mean? Consistent direction and speed
Tell three ways velocity can change. Lose speed, Gain speed, or change in direction
If an object’s mass increases, its acceleration will ______________. Increase
Force = _________ x ____________ Mass x Acceleration
What are unbalanced forces? The net force of balances not equal to 0
What are balanced forces? The net force of balances equal to 0
Net force = _______________ The sum of all forces on an object
What type of force does not cause acceleration? Balanced
What is magnitude? Measurement of maximum motion
What is vector? Having direction as well as magnitude
Explain Newton’s First Law of Motion. Any object in motion will stay in motion until an outside unbalanced force acts upon it
Greater mass = __________ inertia Greater intertia
Explain Newton’s Second Law of Motion. When a force acts on an object the object will accelerate in the direction of the force
Explain Newton’s Third Law of Motion. For every force or reaction there is an equal and opposite force or reaction
What is inertia? The tendency to remain the same
What is another name for Newton’s First Law of Motion? Newton’s first law of inertia
What does air resistance depend upon? The speed and surface area of an object
What is the formula for velocity? Distance/Time
What is the difference between speed and velocity? Velocity includes speed and direction Speed does not include direction but distance and time
What is the difference between mass and weight? Mass is the amount of matter in an object Weight is how heavy something is
How does your mass on Earth compare to your mass on the moon? It is the same
How does your weight on Earth compare to your weight on the moon? It is less because there is less gravity
Explain friction. How does it affect the movement of an object? Friction is the resistance based on what the surface is made out of. It slows objects down
How does the mass of an object affect the amount of force needed to accelerate the object? It increases it
Explain how to solve a vector diagram (to determine a net force). Subtract to find the difference
