What is the difference between distance and displacement?

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

• Distance is the shortest distance between two points, while displacement is the shortest distance between the initial and final positions.

• Distance is the total length of the path traveled, while displacement is the total length of the path traveled.

• Distance is the shortest distance between two points, while displacement is the total length of the path traveled.

Define speed and velocity.

• Speed is the rate at which an object changes its position, while velocity is the rate at which an object covers distance.

• Speed and velocity are the same thing.

• Speed is the rate at which an object covers distance, while velocity is the rate at which an object changes its position in a specific direction.

• Speed is only applicable to objects in motion, while velocity is only applicable to objects at rest.

What is acceleration and how is it calculated?

• Acceleration is the rate of change of speed with respect to distance, and it is calculated using the formula: acceleration = (final speed - initial speed) / distance

• Acceleration is the rate of change of position with respect to time, and it is calculated using the formula: acceleration = (final position - initial position) / time

• Acceleration is the rate of change of time with respect to velocity, and it is calculated using the formula: acceleration = (final time - initial time) / velocity

• Acceleration is the rate of change of velocity with respect to time, and it is calculated using the formula: acceleration = (final velocity - initial velocity) / time

Explain the concept of free falling objects.

• Free falling objects are those that are propelled upwards by a force other than gravity

• Free falling objects experience a decrease in acceleration as they fall

• Free falling objects are those that are falling under the sole influence of gravity, with no other forces acting upon them. This means that the only acceleration experienced by the object is due to gravity, and it falls at a constant rate of 9.8 m/s^2.

• Free falling objects are not affected by air resistance

State Newton's First Law of Motion.

• An object at rest will start moving on its own

• An object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• An object in motion will eventually come to a stop

• An object in motion will change direction without any external force

What is inertia and how does it relate to Newton's First Law?

• Inertia is the tendency of an object to resist changes in its motion. It relates to Newton's First Law as it states that an object at rest will stay at rest, and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

• Inertia is the tendency of an object to slow down when a force is applied to it

• Inertia is the tendency of an object to change direction when a force is applied to it

• Inertia is the tendency of an object to speed up when a force is applied to it

State Newton's Second Law of Motion.

• The force acting on an object is equal to the mass of the object multiplied by its velocity. F = mv

• The force acting on an object is equal to the mass of the object divided by its acceleration. F = m/a

• The force acting on an object is equal to the mass of the object multiplied by its acceleration. F = ma

• The force acting on an object is equal to the mass of the object multiplied by the distance it travels. F = md

What is the relationship between force, mass, and acceleration?

• The relationship between force, mass, and acceleration is given by the equation F = 2ma

• The relationship between force, mass, and acceleration is given by the equation F = m/a

• The relationship between force, mass, and acceleration is given by the equation F = ma, where F is the force applied to an object, m is the mass of the object, and a is the acceleration of the object.

• The relationship between force, mass, and acceleration is given by the equation F = am^2

Explain the concept of drag force.

• Drag force is a force that opposes the motion of an object through a fluid, such as air or water. It is caused by the interaction between the object and the fluid, and it increases with the speed of the object and the density of the fluid.

• Drag force is only caused by the interaction between the object and the fluid

• Drag force decreases with the speed of the object and the density of the fluid

• Drag force is a force that helps the motion of an object through a fluid

Explain the difference between speed and velocity.

• Speed is the rate at which an object changes its position, while velocity is the rate at which an object covers distance.

• Speed and velocity are interchangeable terms.

• Speed is the rate at which an object covers distance, while velocity is the rate at which an object changes its position in a specific direction.

• Speed is only applicable to objects in motion, while velocity is only applicable to objects at rest.
