Kinematics

What is Kinematics?

• Kinematics is the study of forces acting on objects.

• Kinematics is the branch of physics that describes the motion of objects without considering the forces that cause the motion.

• Kinematics focuses on the energy transformations in moving objects.

• Kinematics is the analysis of the effects of gravity on motion.

What is displacement?

• The total distance traveled by an object regardless of direction.

• The shortest distance from the initial to the final position of an object, along with the direction.

• The distance an object moves in a straight line without considering direction.

• The average speed of an object over a period of time.

What is velocity?

• The speed of an object in a straight line.

• The displacement of an object per unit of time, expressed as a vector quantity.

• The total distance traveled by an object regardless of direction.

• The rate at which an object accelerates.

What is non-uniform motion?

• Non-uniform motion occurs when an object travels equal distances in equal intervals of time.

• Non-uniform motion occurs when an object travels unequal distances in equal intervals of time.

• Non-uniform motion is when an object moves in a straight line at a constant speed.

• Non-uniform motion is when an object changes direction but maintains a constant speed.

What is distance?

• Distance is the total length of the path traveled by an object, regardless of direction.

• Distance is the shortest path between two points.

• Distance is a measure of how far apart objects are in space.

• Distance is the amount of space between two objects at rest.

What is the formula for calculating distance?

• distance = speed × time

• distance = time ÷ speed

• distance = speed + time

• distance = speed - time

What is free fall?

• The motion of an object under the influence of gravitational force only, with no other forces acting on it.

• The motion of an object moving upwards against gravity.

• The motion of an object that is thrown and follows a curved path.

• The motion of an object that is stationary and not moving.

What is uniform motion?

• A type of motion where an object travels varying distances in equal intervals of time.

• Uniform motion occurs when an object travels equal distances in equal intervals of time.

• A motion that involves acceleration and deceleration.

• A type of motion that is only applicable to circular paths.

What is the difference between scalar and vector quantities?

• Scalar quantities have only magnitude, while vector quantities have both magnitude and direction.

• Scalar quantities have both magnitude and direction, while vector quantities have only magnitude.

• Scalar quantities are always positive, while vector quantities can be negative.

• Scalar quantities can be represented as arrows, while vector quantities cannot.

What is acceleration?

• Acceleration is the rate of change of velocity per unit of 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.
