Forces and Motion

Front

What force are you demonstrating when you pull a cup towards you?

Back

Applied Force: The force exerted by a person or object to move another object.

Front

What is the support force exerted upon an object that is in contact with another stable object?

Back

Normal Force: The force that supports the weight of an object resting on a surface.

Front

Magnetic Force is an example of ____________ force.

Back

Non-contact Force: A force that acts at a distance without physical contact.

Front

Which of the following is NOT a non-contact force?

Back

Applied Force: A force that requires direct contact to act on an object.

Front

Newton's 3rd law states that for every action, there is an ______ reaction.

Back

Equal & Opposite Reaction: For every action force, there is a reaction force that is equal in size and opposite in direction.

Front

What is gravitational force?

Back

Gravitational Force: The force of attraction between two masses, such as the Earth and an object.

Front

What is friction?

Back

Friction: A force that opposes the motion of an object when it is in contact with another surface.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced Forces: Forces that are equal in size and opposite in direction, resulting in no change in motion. Unbalanced Forces: Forces that cause a change in motion.

Front

What is an example of a contact force?

Back

Contact Force: A force that requires physical contact, such as pushing a door.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = m x a) - This formula shows how force is related to mass and acceleration.
