At which line is the object returning back to the starting point?

What is the displacement of this object?

• 16

• 0

• 45

• 4

Answer explanation

Displacement is the change in position of an object. If the object returns to its starting point, the displacement is 0. Since the correct answer is 0, it indicates no net change in position.

Bill runs 400 meters to Andy's house, turns around, and runs 400 meters back home (Returns).  What is Bill's displacement?

• 0 meters

• 400 meters

• 700 meters

• 1600 meters

Answer explanation

Bill runs 400 meters to Andy's house and then 400 meters back home. His starting and ending points are the same, resulting in a displacement of 0 meters, as displacement measures the shortest distance from the initial to final position.

What is a difference between distance and displacement

• Ohio

• They are the same

• Distance is the total path an object in motion covers, regardless of direction. Displacement the length of a straight line between the starting and ending points.

• Distance can be equal to infinite when only a small distance has been travelled

Answer explanation

The correct choice explains that distance is the total path covered by an object, while displacement is the straight line between the starting and ending points, highlighting their distinct definitions.

What is the distance of an object if: 200 MPH is the speed in 3 Hours ?

• 100

• 400

• 0.03

• 600

Answer explanation

To find the distance, use the formula: Distance = Speed × Time. Here, Speed = 200 MPH and Time = 3 hours. Thus, Distance = 200 × 3 = 600 miles. Therefore, the correct answer is 600.

Velocity is 

• Speed Plus No Cap

• Direction and displacement

• Speed with a direction

• Displacement with a speed

Answer explanation

Velocity is defined as speed with a direction. It indicates not just how fast an object is moving, but also the direction in which it is moving, making 'Speed with a direction' the correct choice.

Polar bears are extremely good swimmers.  If a polar bear is swimming with an average of 4 m/s, how far will it have traveled after 110seconds?

• 27.5 M

• 440 m

• .03 m

• 456.3 m

Answer explanation

To find the distance traveled, use the formula: distance = speed × time. Here, speed = 4 m/s and time = 110 s. Thus, distance = 4 m/s × 110 s = 440 m. Therefore, the correct answer is 440 m.

A car travels 50 miles/hr for 3 hours, calculate the distance it will travel

• 150 miles

• 16.7 miles

• 600 miles

• 90 km

Answer explanation

To find the distance traveled, multiply speed by time: 50 miles/hr * 3 hours = 150 miles. Thus, the correct answer is 150 miles.
