Newton’s First Law (Inertia)
This law states that an object will remain at rest or in uniform motion unless acted upon by an unbalanced force.
What is Newton's First Law?
The formula representing Newton's Second Law.
What is F = ma (Force equals mass times acceleration)?
The force that propels a rocket upward as exhaust gases are expelled downward.
What is the reaction force?
The force that opposes motion between two surfaces in contact.
What is friction?
This safety device in cars helps counteract inertia during sudden stops.
What is a seatbelt?
An example of this law is when a book remains stationary on a table until someone pushes it.
What is inertia?
If you double the mass of an object while keeping the force constant, this happens to the acceleration.
What is it halves?
When you jump off a small boat, the boat moves backward because of this principle.
What is action and reaction?
The force that attracts objects toward the center of the Earth.
What is gravity?
A soccer ball remains stationary until kicked. This illustrates which law?
What is Newton's First Law?
This property causes a soccer ball to stop rolling when friction is applied.
What is resistance?
The SI unit of force.
What is the Newton (N)?
A swimmer pushes water backward to move forward. The backward push is called this.
What is action force?
When forces on an object are equal in size but opposite in direction, they are described as this.
What are balanced forces?
Pushing a shopping cart requires more force when it's full compared to when it's empty. This demonstrates which law?
What is Newton's Second Law?
If a spaceship is drifting in space far from any planet, it will continue to do so forever. What might cause it to change direction?
What are External Forces? (Gravitational/Resistive/Collisions)
An object with a mass of 10 kg accelerates at 2 m/s². Calculate the force applied.
What is 20 N?
Two skaters push off from one another on ice and glide in opposite directions. The distance each skater moves is determined by this property.
What is mass and force applied?
If an object is accelerating, the forces acting on it are described as this.
What are unbalanced forces?
When you paddle a canoe, the canoe moves forward as water is pushed backward. This is an example of which law?
What is Newton's Third Law?
This term describes the sum of all forces acting on an object.
What is net force?
This term describes the rate of change of velocity.
What is acceleration?
When a hammer strikes a nail, the nail exerts this force back on the hammer.
What is an equal and opposite force?
The vector quantity representing the total of all forces acting on an object.
What is net force?
A satellite orbiting Earth continues its motion due to this property, unless acted upon by another force.
