Week 22 Notebook Review Quiz: Newton's Laws & Motion Graphs

What is the SI unit for force?

• Newton
• Joule
• Watt
• Pascal
• Gram

If an object is not moving, what can be said about the forces acting on it?

• They are balanced.
• They are unbalanced.
• No forces are acting on it.
• Only gravity acts on it.

What happens when unbalanced forces act on an object?

• The object remains at rest.
• The object changes its motion.
• The object resists any force.
• The object slows down and stops.

What does Newton’s First Law of Motion state?

• An object at rest stays at rest unless acted upon by an external force.
• Acceleration is produced when a force acts on a mass.
• For every action, there is an equal and opposite reaction.
• Objects always move at a constant velocity.

Which graph shows an object at rest?

• A horizontal line on a distance-time graph
• A slanted upward line on a distance-time graph
• A curved line on a speed-time graph
• A downward-sloping velocity-time graph
