Unit 6 Test Review- Newton's 2nd and Momentum

How can Newton's second law be represented  mathematically? 

• F=MA

• M= F/A

• A= F/M

• All are correct

Why would one ball accelerate more than the other when pushed with the same amount of force?

• Different weights

• Different forces

• Different masses

• Different sizes

According to Newton's second Law, which would take more force to slow down?

• The silver car

• The green car

• They would both take the same force

Which of these best states Newton's Second Law?

• The greater the mass of an object the greater the force needed to change its motion.

• The greater the mass of an object the less force needed to change its motion.

• The mass of an object does not effect the force needed to change its motion

One kg multiplied by m/s² can also be expressed as 1 __________.

• direction

• mass

• kilogram²

• newton

Which of these cars has no acceleration ?

• A car shortly after a stoplight turns green.

• A car approaching a red light

• A car with the cruise control set at 80 km/h

• A car turning a curve at a constant speed

What happens to the speed of the wagon as the rain collects inside of it?

• it decreases

• it remains constant

• it increases

A car designer wants to advertise that his car can accelerate at 25 m/s². The first model only accelerates at 23 m/s^2. What law should he consider to fix the problem?

• 1

• 2

• 3

A push or a pull is called a

• Gravity

• Force

What is Newton's 2nd Law?

• For every action there is an equal and opposite reaction.

• Acceleration depends on two variables, the mass of the object and the amount of force.
