Physics: Linear Motion with Constant Acceleration

Constant Acceleration

The acceleration of an object is proportional to force (F = ma) - thus, if there is a constant force applied onto an object, the object will accelerate at a constant rate.

Kinematics Equations

Linear motion equations that apply in ONE dimension (x-Direction or y-Direction)

Acceleration Equation

a = 𝚫v/𝚫t

Displacement Equation

𝚫x = vt

Displacement Equation (2)

Displacement Equation (3)

Velocity Equation

- Don't need to memorize, just understand conceptually.

Don't Know Time Equation

When Considering Gravity

- Gravity means that there is acceleration in the direction of gravity (center of earth) = -10 m/s²

Throwing Something in Air

Object's highest pony is reached when its vertical velocity equals zero.

Free Falling Object

Object has no acceleration in x-Direction but will have an acceleration in the y direction of -10 m/s².

Projectile Motion

- Occurs when object has velocity in both x & y components.

- Equations must be applied to each separately (x & y are independent of each other)

- Gravity affects only y-Component of Velocity
