force
A push or pull on an object that can cause it to accelerate.
What is a force?
This law states that an object in motion stays in motion unless acted upon by an external force.
What is Newton’s First Law of Motion?
This term describes the size or amount of a physical quantity?
What is magnitude?
Write 5,000 in scientific notation.
What is 5 × 10^3
This scientist formulated three laws describing planetary motion.
Who is Johannes Kepler?
The force that acts against motion between two touching surfaces.
What is friction?
The tendency of an object to resist a change in its motion.
What is inertia?
The measure of the amount of matter in an object.
What is mass?
What a longer force vector represents in a free-body diagram
What is the force with a greater magnitude?
A satellite stays in orbit due to the balance between these two factors.
What are gravity and inertia?
This force pulls objects toward the center of Earth or any other massive body.
What is gravity?
The law described by the formula F=ma
What is Newton’s Second Law of Motion?
A diagram showing all the forces acting on an object.
What is a free-body diagram?
Express 3.2 × 10^(-4) as a single decimal number
What is 0.00032?
What is 0.00032?
Astronauts feel weightless in space because they are in a constant state of this.
What is free-fall?
The supporting force exerted by a surface perpendicular to the object.
What is the normal force?
The acceleration directed toward the center of a circular path.
What is centripetal acceleration?
This force is transmitted through a rope, string, or cable when it is pulled tight.
What is tension?
he forces included in a free-body diagram of a box being pushed across a surface?
What is gravity, normal force, applied force, and friction?
The motion of Earth's tides is primarily dictated by this celestial body's gravitational pull.
What is the Moon?
A force applied directly to an object through physical contact.
What is an applied force?
When the net force on an object is zero, the object is said to be in this state.
What is equilibrium?
This law explains the gravitational attraction between two masses.
What is Newton’s Law of Universal Gravitation?
This is the scientific notation for the gravitational constant, approximately 0.0000000000667.
What is 6.67 × 10^(-11)
According to Kepler’s Second Law, a planet moves faster when it is at this point in its orbit.
