Force and Motion

Front

A push, pull, friction or gravity are all examples of..

Back

force

Answer explanation

A push, pull, friction, or gravity are all types of force. They cause objects to move or change their motion, aligning with the definition of force in physics.

Front

A force that acts on an object to slow or stop its motion

Back

friction

Answer explanation

Friction is the force that opposes motion between two surfaces in contact. It acts to slow down or stop moving objects, making it the correct answer to the question.

Front

The speed and direction of an object is known as its

Back

velocity

Answer explanation

The speed and direction of an object is defined as its velocity. Unlike momentum, which involves mass and velocity, or inertia and mass, velocity specifically describes how fast and in what direction an object is moving.

Front

The distance an object can travel in a specific amount of time is its

Back

speed

Answer explanation

The distance an object travels in a specific time is defined as its speed. Speed measures how fast an object moves, making it the correct choice over motion, position, or inertia.

Front

The amount of matter an object has is its

Back

mass

Answer explanation

The amount of matter in an object is referred to as its mass. Mass is a fundamental property that quantifies how much matter is present, distinguishing it from concepts like velocity, inertia, and momentum.

Front

An increase in speed or a change in velocity is

Back

acceleration

Answer explanation

An increase in speed or a change in velocity is defined as acceleration. It measures how quickly an object's velocity changes over time, making it the correct choice in this context.

Front

The change in the position of an object is

Back

motion

Answer explanation

The change in the position of an object is referred to as motion. Motion describes how an object moves from one place to another, distinguishing it from concepts like direction, momentum, and friction.

Front

Equal forces acting in opposition to each other where no movement is created is a

Back

balanced force

Answer explanation

Balanced forces are equal in magnitude and opposite in direction, resulting in no net force and no movement. This is why the correct answer is 'balanced force'.

Front

The location of an object is its

Back

position

Answer explanation

The location of an object refers to its position in space. Position indicates where an object is situated, while velocity, motion, and momentum describe aspects of its movement, not its specific location.

Front

The tendency of an object that is at rest to stay at rest or if in motion to stay in motion is

Back

inertia

Answer explanation

The correct answer is inertia, which is the property of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion continues in motion unless acted upon by an external force.
