FORCES
What is a force?
A push or pull on an object.
What is motion?
The change in position of an object over time.
What is an interaction?
A mutual action between two or more objects.
Where do we see forces?
In everyday activities like walking or driving.
What does stability mean?
The ability of an object to maintain its position.
What is gravity?
A force that pulls objects toward the Earth.
What is speed?
The distance an object travels per unit of time.
What is friction?
A force that opposes motion between two surfaces in contact.
How do we use friction?
To slow down or stop movement.
What is equilibrium?
A state where all forces acting on an object are balanced.
What are balanced forces?
Forces that are equal in size but opposite in direction.
What is velocity?
The speed of an object in a specific direction.
What is a contact force?
A force that requires physical contact between objects.
What is Newton's First Law?
An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a force.
What affects stability?
The object's base, center of mass, and height.
What are unbalanced forces?
Forces that cause an object to change its motion.
What is acceleration?
The rate at which an object changes its velocity.
What is a non-contact force?
A force that acts at a distance, like gravity.
What is Newton's Second Law?
The acceleration of an object depends on the mass and the force applied (F=ma).
What is a stable object?
An object that returns to its original position after being disturbed.
How do forces affect motion?
They can change the speed or direction of an object.
How does mass affect motion?
How does mass affect motion?
Give an example of an interaction.
A soccer ball being kicked by a player.
How do engineers use forces?
To design structures and machines that can withstand loads and stresses.
How can forces change stability?
How can forces change stability?
