Motion Mastery

What are the different types of motion?

• random motion

• linear motion, circular motion, periodic motion, rotational motion

• zigzag motion

• elliptical motion

Define speed and velocity. How are they different?

• Speed and velocity are the same thing.

• Speed is scalar, velocity is vector.

• Velocity is scalar, speed is vector.

• Speed is a measure of distance, velocity is a measure of time.

Explain the concept of acceleration.

• Acceleration is the speed of an object.

• Acceleration is the force acting on an object.

• Acceleration is the rate of change of velocity with respect to time.

• Acceleration is the distance traveled divided by the time taken.

State Newton's first law of motion.

• An object will change its velocity when acted upon by an external force.

• An object will accelerate when acted upon by an external force.

• An object will move in a circular path unless acted upon by an external force.

• An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.

According to Newton's second law of motion, what is the relationship between force, mass, and acceleration?

• Force divided by mass equals acceleration

• Force equals mass multiplied by acceleration (F = ma)

• Acceleration equals force multiplied by mass

• Mass divided by force equals acceleration

How does Newton's third law of motion explain the interaction between two objects?

• Newton's third law explains that objects attract each other based on their masses.

• Newton's third law states that objects in motion tend to stay in motion.

• Newton's third law describes the relationship between an object's speed and its acceleration.

• Newton's third law explains that the interaction between two objects involves each object exerting an equal and opposite force on the other.

What is the formula to calculate speed?

• Speed = Time / Distance

• Speed = Distance + Time

• Speed = Distance x Time

• Speed = Distance / Time

How is velocity different from speed?

• Speed is used in physics, while velocity is used in chemistry.

• Velocity is measured in kilometers per hour, while speed is measured in meters per second.

• Velocity includes direction, while speed does not.

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

If an object is accelerating, what does that mean about its motion?

• The object is at rest

• The object is moving at a constant speed

• The object is decelerating

• The object is changing its velocity over time.

What is the SI unit of force?

• Joule

• Volt

• Watt

• Newton (N)
