Review: Newton's 2nd Law of Motion

Acceleration depends on the object's mass and on the net force acting on the object. What law of motion is this?

• 2nd Law

• 1st Law

The rate at which velocity changes is

• acceleration

• speed

The equation for acceleration is

• A = ma

• A = f/m

Speed in a given direction is

• velocity

• acceleration

Force is measured as

• N

• m/s

To increase the acceleration, you

• decrease mass, decrease force

• decrease mass, increase force

A greater applied force is required to move an object with a greater mass than one with a smaller mass.

• True
• False

The SI units for force are...

• Newtons

• Meters per second

Acceleration is caused by a force acting on a mass.

• Newton’s first law of motion

• Newton’s second law of motion
