Exploring Basic Physics Concepts

What is the main difference between distance and displacement?

• Displacement is a scalar quantity, distance is a vector quantity.

• Displacement includes direction, distance does not.

• Distance includes direction, displacement does not.

• Distance is always negative, displacement is always positive.

If a car travels 200 miles, what is being described?

• Velocity

• Distance

• Speed

• Displacement

What does speed tell you?

• The total distance divided by the total time.

• The change in velocity over time.

• How far an object has traveled in a specific direction.

• How fast an object is moving.

Which of the following is true about velocity?

• Velocity is the same as speed.

• Velocity includes both magnitude and direction.

• Velocity is a scalar quantity.

• Velocity is always positive.

What does acceleration measure?

• The total distance traveled by an object.

• The total time taken to travel a certain distance.

• The change in velocity over time.

• The speed of an object in a specific direction.

What happens to an object when its velocity and acceleration have opposite signs?

• The object speeds up

• The object slows down

• The object remains at constant speed

• The object changes direction

What is the gravitational acceleration on the Moon?

• 9.8 meters per second squared

• -9.8 meters per second squared

• -1.6 meters per second squared

• 1.6 meters per second squared

In projectile motion, which component of velocity remains constant?

• Neither component

• Both components

• Horizontal component

• Vertical component

According to Newton's first law, what will happen to an object in motion if no external force acts on it?

• It will eventually stop

• It will accelerate

• It will continue in motion

• It will change direction

If a 10 kg box is pushed with a force of 80 N, what is its acceleration?

• 0.8 meters per second squared

• 8 meters per second squared

• 10 meters per second squared

• 80 meters per second squared
