Inertia
This law is about inertia
What is Newton's 1st Law of Motion?
Inertia is directly related to this.
What is mass?
This means an object is at rest on a distance-time graph.
What is a horizontal line?
This is how we calculate distance travelled.
What is speed x time?
This is the average speed for a trip that took 5 hours to go 400 km.
What is 80 km/h?
This is the scientist who described the effect of inertia.
Who is Sir Isaac Newton?
More of this is needed to change the motion of objects with more mass.
What is force?
This means an object is moving at a constant speed on a speed-time graph.
What is a straight horizontal line?
This is how we calculate time of travel.
What is distance divided by speed?
This is the distance travelled if you drive an average of 50 mph for 7 hours.
What is 350 miles.
This type of force will change the motion of an object.
What is an unbalance force?
A body not wearing a seatbelt in a car crash will continue at this until it is stopped by something, such as the windshield.
What is the same speed the car was travelling?
This means that an object is moving at a constant speed moving back towards some reference point on a distance-time graph.
What is a straight line with a negative slope?
This is what we use to calculate the displacement of an object that did not move in a straight line.
What is the Pythagorean theorem? or
What is a2 + b2 = c2
This is the time it would take to walk 2 km moving at a rate of 5 km/h.
What is 0.4 hours or 24 minutes?
This type of force will not change the motion of an object.
What is a balanced force?
Objects will keep moving this way unless acted upon by unbalanced forces.
What is the same speed and direction?
On a distance-time graph, this means the object is accelerating.
What is a curved line?
This is how we would calculate the time if we know the final and initial velocity and the acceleration.
What is t = Vf - Vi / a
This is the rate of acceleration for an object that speeds up from 5 m/s to 13 m/s in 4 seconds.
What is 2 m/s2?
According to the law of inertia, objects resist this.
What is any change in their motion?
An object at rest will stay at rest because of this.
What is inertia?
This means an object is accelerating on a speed-time graph.
What is a straight line with a positive or negative slope (not horizontal)?
This is how we would calculate the final velocity of an object if we knew the acceleration, initial velocity, and the time.
What is Vf = Vi + at
This is the time it would take to reach a velocity of 30 m/s if you jump out of an airplane. (Acceleration of gravity on earth is approximately 10 m/s2).
What is 3 seconds?
