Motion and Forces

What is acceleration?

• Acceleration is the rate of change of velocity over time.

• Acceleration is the speed of an object in a straight line.

• Acceleration is the distance traveled by an object in a given time.

• Acceleration is the force applied to an object divided by its mass.

What is the definition of velocity?

• Velocity is the speed of an object in a specific direction.

• Velocity is the rate of change of an object's position.

• Velocity is the distance traveled by an object over time.

• Velocity is the maximum speed an object can achieve.

What is the formula for calculating acceleration?

• Acceleration (a) = (Final Velocity - Initial Velocity) / Time.

• Acceleration (a) = (Initial Velocity - Final Velocity) * Time.

• Acceleration (a) = Final Velocity / Time.

• Acceleration (a) = (Final Velocity + Initial Velocity) / 2.

What is the definition of speed?

• Speed is the distance traveled per unit of time, regardless of direction.

• Speed is the rate at which an object changes its position.

• Speed is the total distance covered in a journey divided by the total time taken.

• Speed is the measure of how fast something is moving in a specific direction.

What factors affect the acceleration of an object?

• Mass of the object and the net force acting on it.

• The color of the object and the temperature of the environment.

• The shape of the object and the speed of sound.

• The height of the object and the distance from the ground.

What is the relationship between force and acceleration?

• Force = Mass x Acceleration (F = ma)

• Force = Acceleration / Mass (F = a/m)

• Force = Mass + Acceleration (F = m + a)

• Force = Mass - Acceleration (F = m - a)

What is the difference between speed and velocity?

• Speed is a vector quantity (magnitude and direction), while velocity is a scalar quantity (magnitude only).

• Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

• Speed and velocity are the same; both are scalar quantities.

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

How does the direction of motion affect velocity?

• Velocity remains constant regardless of direction changes.

• Velocity changes if the direction of motion changes, even if the speed remains constant.

• Direction of motion has no effect on velocity.

• Velocity is only affected by changes in speed.

What is the difference between distance and displacement?

• Distance is a vector quantity representing the shortest path between two points, while displacement is a scalar quantity representing the total path traveled.

• Distance is a scalar quantity representing the total path traveled, while displacement is a vector quantity representing the shortest path between two points.

• Distance and displacement are the same; both represent the total path traveled.

• Distance is a measure of time taken to travel, while displacement is a measure of speed.

What is instantaneous speed?

• Instantaneous speed is the speed of an object at a specific moment in time.

• Instantaneous speed is the average speed of an object over a period of time.

• Instantaneous speed is the maximum speed an object can achieve.

• Instantaneous speed is the speed of an object when it is at rest.
