Front

What is the correct unit for distance in kinematics?

Back

The correct unit for distance in kinematics is meters (m).

Front

What does a free-body diagram represent?

Back

A free-body diagram represents all the forces acting on an object, showing their direction and magnitude.

Front

What is the maximum height of a ball thrown into the air that takes 8 seconds to return to the same spot?

Back

The maximum height is reached in 4 seconds.

Front

What is the definition of resultant force?

Back

Resultant force is the vector sum of all individual forces acting on an object.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula a = (final velocity - initial velocity) / 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 Newton's first law of motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) x acceleration (a).

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object and is calculated as weight (W) = mass (m) x gravitational acceleration (g).
