Motion
What is the shortest path between two points called?
What is displacement?
What is the formula for speed?
What is speed= distance/time
What does a horizontal line on a position-time graph represent?
What is no motion? (stationary)
Who developed the three laws of motion?
Isaac Newton
What is the formula for momentum?
What is p=mv (momentum=mass x velocity)?
which quantity only has magnitude, not direction?
What is scalar quantity?
How is velocity different from speed?
Velocity includes direction, speed does not
On a position-time graph, what does a steeper line mean?
What is faster motion?
Which law states that an object in motion stays in motion unless acted on by a force?
What is Issac Newton First Law (Law of Inertia)
if velocity doubles, what happens to momentum?
what is it doubles?
What is the difference between distance and displacement?
Distance is the total path traveled , displacement is the straight-line change in position
A car travels 300 km in 3 hours. What is it’s average speed?
what is 100km/h
What does a curved line on a position-time graph mean?
What is acceleration?
What is the formula for force?
What is F=ma (force=mass x acceleration)
Momentum is what quantity?
what is a vector?
True or False: Displacement can be zero even if distance is not
what is true?
what is the unit for velocity in the metric system?
what is meters per second (m/s)
What does a straight , sloped line on a velocity time graph show?
What is constant acceleration?
what is the force that resists motion between surfaces?
What is friction?
What law states that momentum is conserved in a closed system?
what is the law of conservation of momentum?
Give an example of a vector quantity other than displacement
What is velocity
If a runner moves at 5 m/s east for 10 seconds, what is her displacement?
what is 50 meters east?
If a velocity-time graph shows a line sloping down to zero, what is happening?
What is declaration?
If a 10 kg object accelerates at 3 m/s2, what is the net force?
What is 30 N?
Two objects collide and stick together. What kind of collision is it?
What is an inelastic collision?
