Friction & Gravity
This is the type of friction that occurs when the applied force reaches its limit between surfaces and begins to move.
what is sliding friction
This is the combination of all forces acting on an object.
what is the net force
These are the 3 ways an object can accelerate
What are speeding up, slowing down, or changing direction.
this is the measure of the distance an object travels per unit of time.
what is speed
If you are moving towards a reference point, this is the direction you are moving.
what is the positive direction.
The law of universal gravitation states that the level of attraction between two objects depends on these two factors.
What are mass and distance.
This formula we get from Newton's Second Law of Motion.
Acceleration equals force divided by mass or
a=F/m
This is the formula for acceleration
final velocity minus initial velocity over time or
Vf-Vi/t
This is the equation for average speed.
what is distance divided by (or over) time.
This is the starting point you choose to describe a location or position.
what is a reference point
If you want to decrease fluid friction, you must decrease this aspect of an object moving toward the fluid.
What is the surface area.
This is the term used to describe the tendency of an object to resist a change in its motion.
what is inertia
When the initial acceleration arrow is longer than the final acceleration arrow, we can say this about an object's speed.
It is decreasing (or it is slowing down).
These are the two components of velocity
what are speed and direction.
This is the process of changing position.
what is motion.
These are two examples of non-contact forces.
What are gravity and magnets.
If Ms. Moe throws a call that weighs 4kgs with the force of 36N, this would be the acceleration.
What is 9m/s2.
This is the slope of a line representing constant speed on a time-speed graph.
What is 0 (or horizontal).
If the slope of the line on a time-distance graph gets steeper over time, we can tell the object is ____________.
what is increasing speed (or getting faster)
this is the difference between the initial position and the final position of an object
what is displacement.
Let me start by saying the order in this question matters. The first answer is the non-contact force that creates friction. The second answer is the contact force that creates friction
If Ms. Manwani pushed a rock that weighs 12kgs and it accelerated at 3.5m/s2. This is the force she used to push the rock.
What is 42N.
If Mr. Travis is riding his bike at a velocity of 6m/s when my stopwatch is at 3s and 18m/s when my stopwatch is at 7s, this is his acceleration between 3s and 7s.
what is 3m/s2
If a jet leaves New York City at 8:00pm EST, travels 1400 miles and lands at 11:30pm, this will be the jet's average speed.
what is 400 miles per hour
