Newtons Laws of Motion

What is Newton's First Law of Motion?

• An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

• An object will accelerate in the direction of the net force acting on it.

• For every action, there is an equal and opposite reaction.

• An object in motion will eventually come to a stop without external forces.

What is an example of Newton's Second Law in action?

• A heavier object requires more force to accelerate than a lighter object.

• All objects fall at the same rate regardless of their mass.

• An object in motion stays in motion unless acted upon by an external force.

• The acceleration of an object is directly proportional to its mass.

What is the formula for calculating force?

• F = ma (Force equals mass times acceleration)

• F = mv (Force equals mass times velocity)

• F = m/a (Force equals mass divided by acceleration)

• F = m + a (Force equals mass plus acceleration)

What happens when two boys pull a rope with equal force?

• They will not move at all.

• One boy will win and pull the other forward.

• The rope will break due to tension.

• They will both fall backward.

What is Newton's Third Law of Motion?

• For every action, there is an equal and opposite reaction.

• An object in motion stays in motion unless acted upon by an external force.

• The force of gravity is proportional to the mass of the objects involved.

• The acceleration of an object is directly proportional to the net force acting on it.

How does mass affect acceleration?

• Greater mass results in less acceleration for the same amount of force applied.

• Greater mass results in more acceleration for the same amount of force applied.

• Mass has no effect on acceleration regardless of the force applied.

• Acceleration is independent of mass and only depends on the speed.

What is an example of Newton's Third Law in action?

• When you push against a wall, the wall pushes back with equal force.

• A car accelerates when the driver presses the gas pedal.

• A ball rolls down a hill due to gravity.

• A person jumps off a diving board and goes up into the air.

What are unbalanced forces?

• Forces that are equal and opposite, resulting in no change in motion.

• Forces that are not equal and opposite, resulting in a change in motion.

• Forces that act in the same direction, increasing the speed of an object.

• Forces that are always present in a closed system, maintaining equilibrium.

What is Newton's Second Law of Motion?

• The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

• An object at rest will remain at rest unless acted upon by an external force.

• For every action, there is an equal and opposite reaction.

• The velocity of an object is constant unless acted upon by a net force.

What are balanced forces?

• Forces that are equal in size and opposite in direction, resulting in no change in motion.

• Forces that are unequal in size and act in the same direction, causing acceleration.

• Forces that are equal in size and act in the same direction, resulting in increased speed.

• Forces that are opposite in direction but do not have equal size, causing rotation.
