What is 93 km/h?
Draw a distance-time graph that indicates slow constant speed but not stopped.
The meaning of a flat, horizontal line on a speed-time graph.
What is constant speed?
The drop height that will have the most kinetic energy when it reaches the bottom.
What is drop height "A"?
The winners of tug-of-war.
Who are Daniel and Maria?
An elephant travels for 4 hrs at 6.5 km/h and a giraffe travels for 2 hrs at 11 km/h. This animal covers more distance.
What is the elephant?
The most likely explanation for the object's motion during part B.
What is stopped?
The way speed is changing.
What is positive acceleration or increasing speed?
The reason you use an inclined plane to move objects.
What is reduce the amount of force needed to raise an object?
The direction the plane will move if the force of lift is greater than the force of gravity.
What is upwards?
The average speed of a boat that travels 600m in 40s.
What is 15 m/s?
The intervals of time in which the object moving was the fastest.
What is 40s to 60s?
The distance the bus traveled in the first 4 s.
What is 32 m?
The location with the most potential energy.
What is location A (highest point)?
This is the force that slows down a parachute.
What is air resistance?
The time it takes a bike to travel 20 km at 8 km/h. Include units.
What is 2.5 hours?
The average speed during the first 40 seconds of travel. Include units.
What is 0.25 m/s?
Describe the motion of the bus between points B and C.
What is negative acceleration or decreasing speed to a stop?
The best length (long or short) and height (low or high) for an inclined plane to use the least force.
What is long and low?
The direction an object would move if acted upon by these forces.
What is diagonally towards the bottom left?
Your average speed if you paddle a canoe 150 m up a stream for 276 s. Then you turn around and paddle 300 m downstream for 324 s.
What is 0.75 m/s?
The overall average speed of Marie's trip to work.
What is 0.5 mi/min?
The description of this objects movement.
What is increasing speed, maintain a constant speed, then decreasing speed to a stop?
These two properties determine an objects kinetic energy.
What is mass and speed?
