Kinematics Problems

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 formula for calculating distance when acceleration is constant?

Back

Distance (d) = initial velocity (u) * time (t) + 0.5 * acceleration (a) * time (t)^2.

Front

What is the definition of acceleration?

Back

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

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 is the formula for calculating final velocity?

Back

Final velocity (v) = initial velocity (u) + acceleration (a) * time (t).

Front

What does it mean for an object to be in free fall?

Back

An object in free fall is only under the influence of gravity, with no other forces acting on it.

Front

What is the acceleration due to gravity on Earth?

Back

The acceleration due to gravity on Earth is approximately 9.81 m/s².

Front

How do you calculate the time taken for an object to fall a certain distance?

Back

Time (t) = sqrt(2 * distance (d) / acceleration due to gravity (g)).

Front

What is uniform motion?

Back

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

Front

What is the significance of the area under a velocity-time graph?

Back

The area under a velocity-time graph represents the distance traveled by the object.
