Newton's Second Law Test Review

What is Newton's 2nd Law of Motion?

• F=m x a

• An object in motion stays in motion unless acted upon by an outside force

• For every action there is an equal but opposite reaction

What units should mass be in?

• Grams

• Kilograms

• m/s

• Newtons

What units should force be in?

• Kilograms

• Meters

• Newtons

• Grams

What is Newton's First Law of Motion?

• For every action there is an equal but opposite reaction

• F= m x a

• An object in motion stays in motion unless acted upon by an outside force

What kind of relationship do mass and acceleration have?

• Balanced

• Unbalanced

• Cause and Effect

• Inverse

How do you calculate speed?

• Displacement / time

• Distance / time

• Velocity / time

What velocity does an object at rest have?

• It doesn't have velocity, only speed

• 0 m/s

• No way to know

Identical forces are applied to 2 objects. Object A accelerates at a rate of 7 m/s2. Object B accelerates at a rate of 20 m/s2. Who has the larger mass?

• Object A

• Object B

• No way to know

What is acceleration due to gravity?

• 25 m/s2

• 12 m/s2

• 9.8 m/s2

• 0 m/s2

If forces are unbalanced on an object, what is that object doing?

• At rest

• Accelerating

• Has a constant velocity
