what direct information can you get from a pt-graph
what is, position, direction of motion, distance and displacement
An object is moving along with a velocity of -3.96 m/s. It accelerates at 0.87 m/s/s for a time period of 3.50 s. What is the displacement of this object over this time period? Answer Choices A)-3.20 m B) -13.86 m C)-8.53 m
C)-8.53 m
what is Newton's first law?
what is: if an object is at rest it will stay at rest unless acted on by an external force
what is -10m/s2
what 2 languages must you typically be able to speak in order to become an astronaut
what is english and russian
what does kinematics study
what is how objects move
An object is traveling along with a velocity of 5.16 m/s when it accelerates at -1.51 m/s/s for a time period of 6.63 s. What is the final velocity of this object? Answer Choices A)-2.66 m/s B) -10.01 m/s C)-4.85 m/s
C)-4.85 m/s
what is newtons 3rd law?
what is: every action has an equal and opposite reaction
you are pulling a mass of 10kg along a frictionless surface. the block starts from rest and reaches a top speed of 15m/s after being pulled for 20 seconds. what is the net force acting on the mass
what is 7.5 N
Rate of Change of the position of an object
what is velocity
An object is moving along with a velocity of -0.93 m/s. It accelerates at 0.05 m/s/s for a time period of 3.81 s. What is the displacement of this object over this time period? Answer Choices A)-3.18 m B)-2.81 m C)-3.54 m
A)-3.18 m
dynamics is the study of what?
what is, why objects move
kinematics also can be used for rotational motion like a wheel, what type of acceleration and position is used for rotational motion
what is angular acceleration and angular displacement
An object is traveling along with a velocity of 6.34 m/s when it accelerates at 1.57 m/s/s for a time period of 5.22 s. What is the final velocity of this object? Answer Choices A)7.99 m/s B)14.53 m/s C)8.19 m/s
B)14.53 m/s
can an object be at rest if both you and the object are moving? why or why not
what is: yes technically. if your frame of reference is moving at the same exact rate as the object is moving than it can appear to be at rest even though it is still moving (relativity)
