What is the effect of a positive slope on a position vs. time graph?

The object is moving in the positive direction.

What is the effect of a negative slope on a velocity vs. time graph?

The object is slowing down (decelerating).

What is the effect of gravity on an object thrown upwards near Earth's surface?

The object experiences a constant downward acceleration of approximately 10 m/s².

What happens to the maximum height of a projectile if gravity is halved?

The maximum height doubles.

What is the effect of constant acceleration on an object's velocity?

The object's velocity changes uniformly over time.

How do you determine velocity from a position vs. time graph?

Calculate the slope of the line at a specific point. Slope = velocity.

How do you determine displacement from a velocity vs. time graph?

Calculate the area under the curve of the velocity vs. time graph.

How do you determine change in velocity from an acceleration vs. time graph?

Calculate the area under the curve of the acceleration vs. time graph.

What is the first step in solving a kinematic equation problem?

Identify the known variables (initial velocity, final velocity, acceleration, time, displacement) and the unknown variable you need to find.

What is the second step in solving a kinematic equation problem?

Choose the kinematic equation that includes the known variables and the unknown variable.

Define instantaneous velocity.

The rate of change of position with respect to time at a specific instant; mathematically, vx=dxdtv_{x}=\frac{d x}{d t}vx​=dtdx​.

Define instantaneous acceleration.

The rate of change of velocity with respect to time at a specific instant; mathematically, ax=dvxdta_{x}=\frac{d v_{x}}{d t}ax​=dtdvx​​.

What is displacement?

The change in position of an object. On a velocity vs. time graph, it's the area under the curve: Δx=∫t1t2vx(t)dt\Delta x=\int_{t_{1}}^{t_{2}} v_{x}(t) d tΔx=∫t1​t2​​vx​(t)dt.

Define gravitational acceleration (g).

The constant downward acceleration experienced by objects near Earth's surface due to gravity, approximately g≈10 m/mathrms2g \approx 10 \mathrm{~m} / mathrm{s}^{2}g≈10 m/mathrms2.

What are kinematic equations?

Equations that describe the motion of objects with constant acceleration, relating position, velocity, time, and acceleration.
