Kinematics and Forces review

Front

What is Kinematics?

Back

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

Front

What is the definition of Force?

Back

Force is a push or pull on an object that can cause it to accelerate, change direction, or change shape.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by a net external force.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What does the slope of a velocity vs. time graph represent?

Back

The slope of a velocity vs. time graph represents acceleration.

Front

What is the formula for calculating force?

Back

Force (F) = Mass (m) x Acceleration (a).

Front

What is friction?

Back

Friction is a force that opposes the relative motion of two surfaces in contact.

Front

What is the gravitational force acting on a 10 kg object?

Back

Gravitational Force (Weight) = Mass (m) x Gravitational Acceleration (g), where g = 9.81 m/s². Therefore, Weight = 10 kg x 9.81 m/s² = 98.1 N.

Front

What is the definition of displacement?

Back

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