Motion Basics
What term describes a change in position over time?
Motion
The formula for speed is distance divided by this quantity.
What is time?
A force is defined as a push or this.
What is a pull?
This force resists motion between two surfaces touching each other.
What is friction?
Newton’s First Law is also known as the Law of this.
What is inertia?
This quantity tells how far an object travels, regardless of direction.
What is distance?
Speed with a direction is called this.
What is velocity?
The SI unit of force is this.
What is a newton (N)?
Friction that occurs when an object is not moving.
What is static friction
This law explains why seatbelts are important during sudden stops.
What is Newton’s First Law?
This quantity includes both speed and direction.
What is velocity?
A runner moves 20 m east in 4 seconds. What is their velocity?
What is 5 m/s east?
The formula for force is mass multiplied by this quantity.
What is acceleration?
Friction that acts on a moving object sliding across a surface.
What is sliding friction?
This law states that force equals mass times acceleration.
What is Newton's Second
If an object’s position does not change over time, it is said to be this.
What is at rest?
A bike travels 360 meters in 30 seconds. Calculate its speed.
What is 12 m/s?
Calculate the force on a 5 kg object accelerating at 2 m/s².
What is 10N?
Friction that acts on objects moving through air or water.
What is fluid friction?
This law explains why rockets launch upward.
What is Newton’s Third Law?
A car travels 150 meters in 10 seconds. Calculate its speed.
What is 15 m/s?
Two cars have the same speed, but different velocities because of this.
What is direction?
This happens when forces on an object are equal and opposite.
What are balanced forces?
Name two ways friction can be increased.
Ans vary
According to Newton’s Law of Universal Gravitation, gravity depends on mass and this quantity.
What is distance between objects?
