Gravity, Force, and Newton's Laws of Motion

What are Newton's Laws of Motion?

• Statements that explain how rocks form
• Statements that explain how objects move
• Statements that explain how plants grow
• Statements that explain how animals communicate

Which law is also known as the Law of Inertia?

• 4th Law
• 2nd Law
• 1st Law
• 3rd Law

What does the Law of Inertia state?

• An object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force
• An object will accelerate in the direction of the net force acting on it
• An object will move in the opposite direction of the force applied to it
• For every action, there is an equal and opposite reaction

What is the Law of Acceleration also known as?

• 2nd Law
• 3rd Law
• 4th Law
• 1st Law

What does the Law of Acceleration state?

• An object will move in the opposite direction of the force applied to it
• For every action, there is an equal and opposite reaction
• An object will accelerate in the direction of the net force acting on it
• An object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force

Which law is also known as the Law of Action-Reaction?

• 1st Law
• 2nd Law
• 4th Law
• 3rd Law

What does the Law of Action-Reaction state?

• An object will move in the opposite direction of the force applied to it
• For every action, there is an equal and opposite reaction
• An object will accelerate in the direction of the net force acting on it
• An object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force

How do Newton's Laws apply to a playground swing?

• Sitting still on the swing. You will stay motionless until someone pushes you
• Someone pushing you harder, making you swing faster
• Pumping your legs to gain momentum, and each time you push your legs, the swing pushes back with an equal force
• All of the above

How do Newton's Laws apply to a car and engine?

• None of the above
• When the engine exerts a force on the wheels
• Pressing the gas pedal
• When the car is stationary

The picture is an example of Newton's...

• 1st Law
• 2nd Law
• 3rd Law
