What is the formula for average speed?
Average Speed = Total Distance + Total Time
Average Speed = Total Distance / Total Time
Average Speed = Total Time / Total Distance
Average Speed = Distance x Time
If a car travels 100 km in 2 hours, what is its average speed?
100 km/h
25 km/h
50 km/h
75 km/h
Define acceleration in your own words.
Acceleration is the distance traveled over time.
Acceleration is the force applied to an object.
Acceleration is the change in velocity per unit of time.
Acceleration is the speed of an object at a given moment.
What is the unit of acceleration?
newtons (N)
meters per second (m/s)
kilometers per hour (km/h)
meters per second squared (m/s²)
How do you calculate acceleration?
a = v_f + v_i
a = (v_f - v_i) / t
a = v_i / t
a = (v_f * t) + v_i
What does a horizontal line on a speed graph indicate?
Constant speed
Decreasing speed
No speed
Variable speed
What does the slope of a speed-time graph represent?
Acceleration
Velocity
Time
Distance
What is a reference point in motion?
A reference point is an object that changes position constantly.
A reference point is a moving object used to track speed.
A reference point is a measurement of time in motion.
A reference point is a fixed location used to measure the position and motion of an object.
How can you determine if an object is in motion?
An object is in motion if it is spinning in place.
An object is in motion if it is stationary relative to the ground.
An object is in motion if it is the same color as its surroundings.
An object is in motion if its position changes relative to a reference point.
What is the difference between motion and rest?
Motion is a state of being still; rest is a state of being active.
Motion is the absence of change in position; rest is the change in position.
Motion is the change in position; rest is the absence of change in position.
Motion refers to objects at rest; rest refers to objects in motion.
If a person walks 5 meters forward and then 5 meters back, what is their total displacement?
10 meters
2.5 meters
0 meters
5 meters
What does a speed of 0 m/s indicate about an object's motion?
The object is in free fall.
The object is accelerating in a direction.
The object is at rest.
The object is moving at a constant speed.
How can you represent motion graphically?
Motion cannot be represented graphically.
Motion can be represented using position-time, velocity-time, and acceleration-time graphs.
Motion is best represented with pie charts.
Motion can only be represented using bar charts.
What is the significance of the y-axis on a speed graph?
The y-axis signifies the speed of an object.
The y-axis shows the acceleration of the object.
The y-axis represents time intervals.
The y-axis indicates the distance traveled.
Explain how a change in velocity relates to acceleration.
Acceleration only occurs when velocity is constant.
A change in velocity results in acceleration, as acceleration measures how quickly velocity changes over time.
A change in velocity does not affect acceleration.
Acceleration is the same as velocity.
