What is the key difference between speed and velocity?
What is velocity has a direction and speed does not?
A car speeds up from 10 m/s to 30 m/s in 5 seconds. What is its acceleration?
What is 4 m/s² ?
On a position-time graph, a flat line means that this is occurring
What is the object is not moving?
This equation gives final velocity with time, initial velocity, and acceleration.
What is v=v0+at
The rate of change of velocity.
What is acceleration?
How long would it take a car, starting from rest and accelerating uniformly in a straight line at 5 m/s2, to cover a distance of 200 m ?
What is 8.94 seconds?
If you take the area under an acceleration-time graph, it will give you this
What is the change in velocity?
Using this equation v=v0+at, derive the equation to solve for acceleration
What is a=(v−v0)/t?
The rate of change of displacement
What is velocity?
An object is dropped from rest. What is its velocity after 3 seconds?
What is 30 m/s?
The slope of a velocity-time graph gives this.
What is acceleration?
When an object in motion has 2 different components, which component symbolizes the y-direction?
What is sin?
When acceleration is moving at the same rate and is in a straight line, this type of motion is occurring.
What is uniform acceleration
A soccer ball, at rest on the ground, is kicked with an initial velocity of 10 m/s at a launch angle of 30°. Calculate its total flight time, assuming that air resistance is negligible. Approximate to the nearest second
What is approximately 1 second?
If the slope of a position-time graph is INCREASING and POSITIVE. The object is what?
What is speeding up?
Give that a ball is thrown vertically upward with an initial velocity of 12 m/s. How high does it rise before momentarily stopping?
Which kinematic equation would be best for this question?
What is v2=v02+2aΔx?
This is a vector quantity that describes the change in position.
What is displacement?
An object moves in a straight line. A velocity-time graph shows a triangle from v=0 to v=6 m over 4 seconds, then back to v=0 over the next 2 seconds. What is the total displacement?
What is 18m?
What is the object has a constant velocity?
A student drops a rock from the top of a 30m tall building. Derive an equation for time. DO NOT SOLVE
What is √2Δx / a
OR √2Δx /g
