What is the formula for acceleration?

• a = (v_f * v_i) / t

• a = (v_f + v_i) / t

• a = (v_f - v_i) * t

• a = (v_f - v_i) / t

Explain how to interpret a distance-time graph.

• Find the highest point on the graph

• Look at the color of the graph

• Look at the slope of the graph to determine the speed of the object and the area under the graph to find the distance traveled.

• Count the number of lines on the graph

An object is dropped from a height of 50 meters. How long will it take to reach the ground?

• 1.23 seconds

• 3.19 seconds

• 10.45 seconds

• 5.67 seconds

How is displacement different from distance?

• Displacement measures the total length of the path traveled

• Distance measures the shortest path between two points

• Displacement measures the longest path between two points

• Displacement measures the shortest path between two points, while distance measures the total length of the path traveled.

A train travels at a velocity of 30 m/s for 10 seconds. What is its displacement?

• 600 m

• 150 m

• 300 m

• 50 m

What is the difference between speed and velocity?

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

• Speed and velocity are the same thing

• Speed and velocity both have direction and magnitude

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

How does acceleration affect an object's motion?

• It has no effect on the object's motion

• It changes the object's speed and/or direction.

• It makes the object invisible

• It causes the object to shrink in size

Describe the motion of an object in free fall.

• The object decelerates at a constant rate of 9.8 m/s^2 upward.

• The object moves at a constant speed of 9.8 m/s downward.

• The object accelerates at a constant rate of 5 m/s^2 upward.

• The object accelerates at a constant rate of 9.8 m/s^2 downward.
