Objects in motion will _______________ until acted upon by another force. Remain in motion
Inertia is described by Newton's ________ law of motion. First law of motion
2nd Law https://www.youtube.com/watch?v=xzA6IBWUEDE
F = m X a Force equal mass multiplied by acceleration A heavy object needs more force to accelerate than a lighter object. A line graph is used to show data. Constant speed is a straight line and acceleration is a curved line.
According to Newton's second law of motion, what is the relationship between mass and acceleration? Inversely proportional to each other
Review Balanced and Unbalanced Forces A stationary object is balanced. A moving object with equal opposite forces continues to move. A moving object is unbalanced. Unequal forces on an object also moves.
What might cause a car parked on a hill to start to roll backwards? unbalanced force
Balanced forces are always opposite in ______________. direction
Objects in motion will _______________ until acted upon by another force. (remain in motion) Inertia is described by Newton's ________ law of motion. (1st Law) What might cause a car parked on a hill to start to roll backwards? (unbalanced force) Balanced forces are always opposite in ______________ (direction) According to Newton's second law of motion, what is the relationship between mass and acceleration? (Inversely proportional to each other)
