Physics: Acceleration

Definitions

• Acceleration: a rate at which an objects velocity changes w/ time. vector measurements

• Displacement: distance from starting point

• Acceleration due to gravity: the rate at which an object speeds up as it falls freely toward the earth

• Dropped: Vo is 0

• Velocity: the speed of an object and its direction of motion

Q: if you calculate the slope of a distance vs time graph, what are you “really” calculating?

• A: velocity

Q: if you calculate the slope of a velocity vs time graph, what are you “really” calculating?

• A: acceleration

On a velocity vs time graph, what does it mean when the graph goes flat?

• A: constant velocity
