Force and Motion

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in miles per hour (mph) or meters per second (m/s).

Front

How do you calculate speed?

Back

Speed = Distance / Time. For example, if Mark drives 200 miles in 4 hours, his speed is 200 miles / 4 hours = 50 mph.

Front

What happens to gravitational force as mass increases?

Back

Gravitational force increases as mass increases. This means that heavier objects exert a stronger gravitational pull.

Front

What is gravity?

Back

Gravity is a force of attraction between two objects due to their masses. It pulls objects toward each other.

Front

What is net force?

Back

Net force is the combination of all forces acting on an object. It determines the object's motion.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces that are in contact with each other.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net force.

Front

What is the relationship between force and motion?

Back

Force is any interaction that, when unopposed, will change the motion of an object. A net force acting on an object causes it to accelerate.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It occurs when an object speeds up, slows down, or changes direction.

Front

What is the formula for calculating net force?

Back

Net Force = Mass x Acceleration (F = ma). This formula shows how force, mass, and acceleration are related.
