Warm-Up: Motion Concepts

What is the definition of speed?

• The measure of how quickly an object moves or the distance it covers in a given amount of time.

• The measure of how slowly an object moves or the distance it covers in a given amount of time.

• The measure of how far an object moves in a given amount of time.

• The measure of how quickly an object changes its direction.

What is the definition of velocity?

• Velocity is the rate of change of displacement with respect to time.

• Velocity is the rate of change of speed with respect to time.

• Velocity is the rate of change of time with respect to displacement.

• Velocity is the rate of change of acceleration with respect to time.

What is the difference between distance and displacement?

• Distance is the total time taken to travel, while displacement is the total distance traveled.

• Distance is a scalar quantity, while displacement is a vector quantity.

• Distance is the total length of the path traveled, while displacement is the shortest distance between the initial and final positions.

• Distance is always positive, while displacement can be positive, negative, or zero.

How can you interpret a distance vs. time graph?

• A distance vs. time graph represents the relationship between distance traveled and time taken.

• A distance vs. time graph represents the relationship between acceleration and time.

• A distance vs. time graph represents the relationship between speed and time.

• A distance vs. time graph represents the relationship between displacement and time.

How can you measure and record an object's motion?

• Using a microscope, telescope, or spectrometer.

• Using a scale, thermometer, or compass.

• Using a stopwatch, ruler, measuring tape, video camera, or motion sensor.

• Using a pedometer, altimeter, or barometer.

What is the relationship between speed and velocity?

• Speed and velocity are the same thing.

• Velocity is the square root of speed.

• Speed is a scalar quantity while velocity is a vector quantity.

• Velocity includes both speed and direction, while speed only refers to how fast an object is moving.

If a distance vs. time graph is a straight line with a positive slope, what does it represent?

• constant speed

• rest

• deceleration

• acceleration

If a distance vs. time graph is a horizontal line, what does it represent?

• The object is moving in a circular path.

• The object is not moving or has a constant velocity.

• The object is moving at a constant speed.

• The object is accelerating.
