Scalar? I hardly Know her
This quantity has both magnitude and direction, unlike speed or temperature.
What is displacement, velocity, acceleration, force etc
An object moving at a steady speed in a straight line experiences this net force.
What is zero newtons?
On a v-t graph, this quantity is represented by the slope.
What is acceleration?
This is the force that gravity exerts on an object.
What is weight?
A book at rest on a table is supported by this upward force.
What is the normal force?
Mass is an example of this type of quantity.
What is a scalar because it only has magnitude
When a car slows down while moving east, this is the direction of its acceleration.
What is west?
This kind of line on a velocity-time graph represents constant velocity.
What is a horizontal line?
An object on a planet with stronger gravity than Earth experiences this change in mass and weight.
What is mass stays the same, weight increases?
A mass hangs motionless from a rope. The tension equals this.
What is the weight of the mass?
Two forces act on an object in opposite directions, 10 N and 6 N. This is the net force.
What is 4 N in the direction of the 10 N force?
Doubling the net force on an object while keeping its mass the same causes this change in acceleration.
What is it doubles?
A line with a positive slope on a velocity-time graph shows this.
What is positive acceleration?
A 5 kg object on Earth has this weight (use g = 10 m/s²).
What is 50 N?
When a hanging object accelerates upward, the tension in the rope is this compared to its weight.
What is greater than its weight?
When two vectors are perpendicular, this theorem gives the net magnitude.
What is the Pythagorean theorem
The velocity-time graph of a ball slowing down at a constant rate has this shape.
What is a straight line with a negative slope?
The area under a velocity-time graph represents this quantity.
What is displacement?
On the Moon, a 10 kg toolbox has this mass and this weight (g = 1.6 m/s²).
What is mass = 10 kg, weight = 16 N?
In an ideal pulley, the tension on both sides of the rope is this.
What is the same?
A plane flies 200 km east and 150 km north. This is the magnitude and direction of its displacement.
What is 250 km at 36.9° north of east?
A car accelerates at 2 m/s² for 5 seconds from rest. This is its final speed.
What is 10 m/s?
The slope of a horizontal line on a speed-time graph tells you this.
What is zero acceleration?
This explains why an object’s weight changes from planet to planet, but its mass does not.
What is weight depends on gravity, mass is intrinsic?
On a frictionless surface, a block pulled by a force accelerates in this direction.
What is the direction of the net force?
