A body undergoes acceleration when there is a change in its state of motion
1. In.5 seconds a projectile goes from m/s. What is the acceleration of the projectile? 2. The space shuttle releases a telescope into orbit around the earth. The telescope goes from being stationary to traveling at a speed of 1700 m/s in 25 seconds. What is the acceleration of the satellite?
m/s / 25 = 68 m/s 2
Velocity vs. Time Graphs
Acceleration= Increasing Velocity
Negative Acceleration= Decreasing Velocity
Acceleration is directly proportional to net (or unbalanced) force.
How do mass and force affect the acceleration of an object?
As one thing gets bigger so does the other!
The amount of matter in an object The measure of the inertia (laziness) of an object
Volume: how much space it takes up Weight: a measure of the force of gravity
F = force m = mass a = acceleration SI Units of Newtons (N) SI Units of Kilograms (kg) SI Units of m/s 2 F=ma
