Forces and Motion Flashcard

Front

What is friction?

Back

Friction is a force that resists the motion of two surfaces that are in contact with each other.

Front

In which section of a motion graph is an object moving away from its starting point?

Back

The object is moving away from its starting point in section X.

Front

How can we compare the speeds of two toy cars based on their motion graphs?

Back

If Car 1's graph shows a steeper slope than Car 2's, then Car 1 traveled faster than Car 2.

Front

What is weight?

Back

Weight is the measure of the gravitational force acting on an object.

Front

What happens to the force exerted by a table when a bowling ball is placed on it?

Back

The force exerted by the table is equal to the downward force of the bowling ball.

Front

What is the formula for calculating weight?

Back

Weight (W) = mass (m) × gravitational acceleration (g).

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 unless acted upon by a net external force.

Front

What is acceleration?

Back

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

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 balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.
