Kinematic Equations in One reading

What do displacement calculations determine?

• Speed

• Acceleration

• Change in position

• Time

Why are kinematic equations important for understanding object motion in one dimension?

• To calculate the acceleration of an object

• To determine the displacement of an object

• To analyze the velocity of an object

• To study the forces acting on an object

what is the equation that has no time?

• A= ( Vf- Vi ) / Δt

• 
  Vf² = Vi² + 2a Δx

• 
  Δx = .5 ( vf+ Vi ) Δt

• Δx = ( Vi Δt) + ( .5 a Δt² )

What aspects of motion can be analyzed using velocity-time graphs?

• Speed and distance

• Acceleration, deceleration, and constant velocity

• Time and position

• Force and energy
