Linear Motion

Front

What is the relationship between force and acceleration in linear motion?

Back

Generally, the more force you apply to an object, the faster it will accelerate.

Front

How does an object's mass affect its acceleration?

Back

An object's mass will affect how fast it can accelerate; a larger mass requires more force to achieve the same acceleration.

Front

What happens to the acceleration of an object when more force is applied?

Back

The acceleration of the object increases.

Front

Define velocity in the context of motion.

Back

Velocity is speed with a direction.

Front

Provide an example of velocity.

Back

A migrating bird headed south for the winter at 3 m/s.

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 second law of motion?

Back

Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

How does friction affect linear motion?

Back

Friction opposes the motion of an object, which can decrease its acceleration.

Front

What is the formula for calculating acceleration?

Back

Acceleration can be calculated using the formula a = (final velocity - initial velocity) / time.

Front

What is the unit of measurement for acceleration?

Back

The unit of measurement for acceleration is meters per second squared (m/s²).
