Newtons 1st Law

What is the difference between balanced and unbalanced forces?

• Balanced forces cause a change in motion, while unbalanced forces do not.

• Balanced forces do not change the motion of an object, while unbalanced forces cause a change in motion.

• Balanced forces are stronger than unbalanced forces.

• Unbalanced forces always act in pairs, while balanced forces do not.

What is an example of Newton's 1st Law in everyday life?

• When a car suddenly stops, passengers lurch forward.

• A ball rolling on the ground eventually comes to a stop due to friction.

• A person pushes a shopping cart, and it moves forward.

• A book resting on a table remains at rest until someone picks it up.

What is a push or pull that can change the motion of an object?

• Force

• Mass

• Velocity

• Acceleration

What is an example of unbalanced forces?

How does mass affect inertia?

• The greater the mass of an object, the greater its inertia.

• Mass has no effect on inertia.

• Inertia decreases as mass increases.

• Inertia is only affected by the speed of the object.

What is the term for forces that are equal in size and opposite in direction?

• Balanced forces

• Unbalanced forces

• Net forces

• Frictional forces

What happens to an object if the net force acting on it is zero?

• The object will accelerate in the direction of the net force.

• The object will maintain its current state of motion.

• The object will come to a stop.

• The object will change its direction of motion.

What is a real-world application of Newton's 1st Law?

• Seatbelts in cars prevent passengers from continuing to move forward in a sudden stop.

• A ball rolling on the ground eventually comes to a stop due to friction.

• A rocket launches into space by pushing against the ground.

• A car accelerates faster when going downhill than on a flat road.

What is the significance of Newton's 1st Law in understanding motion?

• It helps explain why objects behave the way they do when forces are applied.

• It states that all objects in motion will eventually stop.

• It describes the relationship between force and mass.

• It indicates that an object at rest will remain at rest unless acted upon by an unbalanced force.

If an object is stationary, what can we say about the forces acting on it?

• The forces are balanced.

• The forces are unbalanced.

• There are no forces acting on it.

• The forces are in motion.
