Force and Motion Review

Front

What is the definition of force?

Back

A force is a push or pull acting upon an object, resulting from the object's interaction with another object.

Front

What is the unit of force?

Back

The unit of force is the newton (N).

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 it mean for forces to be balanced?

Back

Balanced forces occur when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces occur when two forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur due to a change in speed or direction.

Front

How do you calculate speed?

Back

Speed is calculated by dividing the distance traveled by the time taken (Speed = Distance / Time).

Front

What is the formula for calculating acceleration?

Back

Acceleration is calculated using the formula: Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the relationship between mass and force?

Back

According to Newton's second law, force is equal to mass times acceleration (F = m * a).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; it is directly related to the object's mass.
