Force & Motion Test

1. What is the definition of Newton's 1st Law?

• When an object exerts force on another object, the second object exerts an equal and opposite force on the first object
• The acceleration of an object increases with increased force, decreases with increased mass, and is in the same direction as the force.
• An object at rest stays at rest and an object in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

2. What is the definition of Newton's 2nd Law?

• When an object exerts force on another object, the second object exerts an equal and opposite force on the first object
• The acceleration of an object increases with increased force, decreases with increased mass, and is in the same direction as the force.
• An object at rest stays at rest and an object in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

3. What is the definition of Newton's 3rd Law?

• When an object exerts force on another object, the second object exerts an equal and opposite force on the first object
• The acceleration of an object increases with increased force, decreases with increased mass, and is in the same direction as the force.
• An object at rest stays at rest and an object in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
