Forces and Motion P.1.1 and P.1.2

Front

What is speed?

Back

Speed is the distance traveled per unit of time, usually measured in meters per second (m/s).

Front

How do you calculate speed?

Back

Speed = Distance ÷ Time.

Front

What is the formula for calculating distance?

Back

Distance = Speed × Time.

Front

What is the formula for calculating time?

Back

Time = Distance ÷ Speed.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it comes into contact with another surface.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other, commonly experienced as the force that pulls objects towards the Earth.

Front

What happens to the speed of an object when its mass increases?

Back

The speed of an object may decrease if the force applied remains constant, as more mass requires more force to achieve the same acceleration.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, measured in meters per second squared (m/s²).

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, Force = Mass × Acceleration; if mass increases, acceleration decreases if the force remains constant.

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 force.
