What is mass x acceleration (F = m x a)?

100
The force that causes objects like a bowling ball to fall to the Earth
What is gravity?
100

Daily Double- What is the acceleration of an object that is falling at terminal velocity?

100
A 300 N force acts on a 30 kg object. Th acceleration of the object is ________. (Use correct units)
What is 10 m/s2?
200
F = m x a; acceleration depends on mass and force; Law of Accerleration
What is Newton's 2nd Law of Motion?
200

The greater the force, the greater the _______

What is acceleration?

200

Which object would hit the ground first...a golf ball or a basketball?

What is both would hit the ground at the same time?

200
The tendency of an object to resist change in motion; a property of matter
What is inertia?
200

Daily Double- Increasing force and mass equally and in proportion will increase in acceleration of an object. T or F

What is false? Increasing one or the other will increase acceleration but not both.

300
An object in motion/rest stays in motion/rest unless an outside force acts upon it; Law of Inertia
What is Newton's 1st Law of Motion?
300

The greater the mass, the ______ acceleration

What is less?

300
The acceleration of an object that falls to the ground
What is 9.8 m/s/s?
300
The motion of a falling object when the only force acting on it is gravity
What is free fall?
300
