Physical Science- Force & Motion

Front

What are balanced forces?

Back

Balanced forces are two forces acting on an object that are equal in magnitude and opposite in direction, resulting in no change in motion.

Front

How do you calculate average speed?

Back

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

Front

What is friction?

Back

Friction is a contact force that opposes the motion of an object, slowing it down.

Front

How is an object's position defined?

Back

An object's position is defined as where the object is relative to a reference point.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object over time.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (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 a contact force?

Back

A contact force is a force that acts on an object through direct contact, such as friction or tension.

Front

What is a non-contact force?

Back

A non-contact force is a force that acts on an object without physical contact, such as gravitational force or magnetic force.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces are forces that are not equal in magnitude and/or direction, causing a change in the object's motion.
