Newtons 1st Law Of Motion

1. 1. what does newtons first law of motion state?

• An object will accelerate if no force is applied.
• An object will change direction only if a force is applied.
• An object in motion will eventually stop without any force.
• An object will remain at rest or in uniform motion unless acted upon by an external force.

which concept is most closely related to newtons first law?

• Gravity
• Inertia
• Friction
• Momentum

why does a rolling ball on the ground eventually stop even though newtons first law suggests that it should keep moving?

• The ball stops due to friction acting as an external force.
• The ball gains speed due to gravity.
• The ball is pushed by an invisible force.
• The ball is rolling uphill against friction.

if you are in a moving car that suddenly stops why do you continue moving forward?

• You are thrown by the car's brakes.
• You are pushed by the car's engine.
• You are pulled by gravity.
• You continue moving forward due to inertia.

which situation best illustrates newtons first law?

• A car accelerating on a highway.
• A ball thrown in the air.
• A person pushing a shopping cart.
• A hockey puck sliding on ice.

why is wearing a seatbelt important in relation to newtons first law?

• Seatbelts are only necessary for long trips.
• Wearing a seatbelt increases the risk of injury during a crash.
• Seatbelts are designed to keep passengers comfortable, not safe.
• Wearing a seatbelt is important because it restrains occupants and prevents them from being thrown forward in a crash, aligning with Newton's first law.
